Installed to custom prefix, can't import tesseract module

I am running on a redhat system where I do no have admin priviledges or 
priviledges to write to /usr/local.  Instead, I have recreated the /usr 
directory structure under /foo/bar/usr where /foo/bar is a directory i have 
full rwx priviledges.  I had to build and install from source python 2.7.3 and 
swig 2.0.8 to the /foo/bar/usr.  Then I repeated these steps for tesseract and 
its dependencies.  Then after getting python-tesseract to build and install, I 
can't successfully import the tesseract module.  The output I get is:

The output I get is as follows:

>>> import tesseract
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "tesseract.py", line 26, in <module>
    _tesseract = swig_import_helper()
  File "tesseract.py", line 18, in swig_import_helper
    import _tesseract
ImportError: libtesseract.so.3: cannot open shared object file: No such file or 
directory

Here are the steps I followed:
1. mkdir /foo/bar/usr/local
2. set environment variables with
export CFLAGS=-I/foo/bar/usr/local/include; export 
LDFLAGS=-L/foo/bar/usr/local/lib; export 
LIBLEPT_HEADERSDIR=/foo/bar/usr/local/include
3. Compile and install jpeg-8d, giflib-4.1.6, libpng-1.5.13, tiff-4.0.0, 
zlib-1.2.7, and leptonica-1.69 using this command for each library:
./configure --prefix=/foo/bar/usr/local; make; make install;
4. install python 2.7.3 from source to /foo/bar/usr/local:
./configure --prefix=/foo/bar/usr/local; make; make install;
5. grab tesseract-ocr-read-only from svn compile and install:
./configure --prefix=/foo/bar/usr/local; make; make install;
6. copy tesseract-ocr-read-only/ccutil/tprintf.h to /foo/bar/usr/local/include
7. svn checkout http://python-tesseract.googlecode.com/svn/trunk 
python-tesseract
8. cd python-tesseract
9. modify lines 99 & 100:
incls = ['/usr/include', '/usr/local/include', '/foo/bar/usr/local/include']
libs=['/usr/lib', '/usr/local/lib', '/foo/bar/user-supported/usr/local/lib']
10. build and install python-tesseract running:
python config.py;
python setup.py clean;
python setup.py build;
python setup.py install --prefix=/foo/bar/usr/local

11. Enter python prompt and import tesseract.

The output I get is as follows:

>>> import tesseract
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "tesseract.py", line 26, in <module>
    _tesseract = swig_import_helper()

    import _tesseract
ImportError: libtesseract.so.3: cannot open shared object file: No such file or

then u need to manually copy all the .so into a single directory. I guess it 
will work

I'm trying to figure out from where the module is attempting to load the 
libtesseract.so.3 module.  It is already in my /foo/bar/usr/local/lib and 
permissions are set to 777 just in case.

I solved the problem.  I had to modify the PYTHONPATH to include the custom bin 
directory /foo/bar/usr/local/bin

Interesting....
How about install python-tesseract to user-directory?

python setup.py install --user

Of course, I haven't tried it before

I apologize, I added my lib directory not my bin directory. so my PYTHONPATH = 
/foo/bar/usr/local/lib which is where libtesseract.so is located.  

I attempted to install to user-directory but it does not change anything 
related to the location of libtesseract.so.  If I had compiled tesseract and 
all its dependencies to my user directory, then this may work, but I suspect, I 
would still have to add the user directory containing libtesseract.so to my 
pythonpath

If it is not too much a trouble, please share your successful story (step by 
step preferably) on installing python-tesseract even without an admin right.

a user install would work, but in my particular situation, my user drive does 
not have much space. I am close to finishing my write up on what I did. I had 
to confirm my steps as I did this spread out over several months.  I will post 
soon

Better late than never... I think these are still incomplete, but I no longer 
have the time to fully retest my instructions

In order to setup python-tesseract to a custom prefix, I had to setup a 
completely fresh build environment in a directory where I have permissions.  
Additionally I wanted OpenCV support as well, so I had to build OpenCV as well. 
 I will include the steps I followed for each of these separately.  Assuming 
the directory you have full rights is at /foo/bar.  I chose to install 
tesseract and all dependent libraries to /foo/bar/usr/local.  I had to build 
gcc4.4.7 from source as well because my gcc was producing errors with the 
current version of OpenCV 2.4.3.

Building GCC 4.4.7:
mkdir /foo/bar/sandbox;
cd /foo/bar/sandbox;
svn co svn://gcc.gnu.org/svn/gcc/tags/gcc_4_4_7_release gcc;
cd /foo/bar/sandbox/gcc;
wget ftp://ftp.gnu.org/gnu/gmp/gmp-4.3.2.tar.gz
wget http://www.mpfr.org/mpfr-2.4.2/mpfr-2.4.2.tar.gz
wget http://www.multiprecision.org/mpc/download/mpc-0.8.1.tar.gz
tar -xzf gmp-4.3.2.tar.gz
mv gmp-4.3.2 gmp
tar -xzf mpfr-2.4.2.tar.gz
mv mpfr-2.4.2 mpfr
tar -xzf mpc-0.8.1.tar.gz
mv mpc-0.8.1 mpc
mkdir /foo/bar/sandbox/gcc-build;
cd /foo/bar/sandbox/gcc-build;
/foo/bar/sandbox/gcc/configure --prefix=/foo/bar/usr \
--with-local-prefix=/foo/bar/usr/local
make; 
make install;


Building OpenCV 2.4.3:

cd /foo/bar/sandbox;
wget 
http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.4.3/OpenCV-2.4
.3.tar.bz2/download;
tar -xjf OpenCV-2.4.3.tar.bz2

3. Compile and install jpeg-8d, giflib-4.1.6, libpng-1.5.13, tiff-4.0.0, 
zlib-1.2.7, and leptonica-1.69 using this command for each library:
./configure --prefix=/foo/bar/usr/local; make; make install;

7. svn checkout http://python-tesseract.googlecode.com/svn/trunk 
python-tesseract
8. cd python-tesseract
9. modify lines 99 & 100 of setup.py:
incls = ['/usr/include', '/usr/local/include', '/foo/bar/usr/local/include']
libs=['/usr/lib', '/usr/local/lib', '/foo/bar/user-supported/usr/local/lib']
10. build and install python-tesseract running:
python config.py;
python setup.py clean;
python setup.py build;
