Install error on OSX 10.9.4

[Jerry Cheung]

I have developer tools installed. I ran into #31, but fixed that by referencing my homebrew include path.

The error I see is:

checking for g++... g++
checking whether the C++ compiler works... no
configure: error: in `/opt/rubies/2.1.2-github1/lib/ruby/gems/2.1.0/gems/phashion-1.1.1/ext/phashion_ext/pHash-0.9.6':
configure: error: C++ compiler cannot create executables

Thanks for the neat gem!

@jch hmmmm. tricky.

How did you install Developer Tools on your machine?

How did you install Ruby on your machine?

Where do your /usr/bin compiler commands point to? For me,

  8 lrwxr-xr-x   1 root   wheel       7 Oct 27  2013 c++ -> clang++
 16 -rwxr-xr-x   1 root   wheel   14240 Oct 27  2013 clang++
 16 -rwxr-xr-x   1 root   wheel   14224 Oct 27  2013 clang
...
16 -rwxr-xr-x  1 root  wheel  14224 Oct 27  2013 gcc
16 -rwxr-xr-x  1 root  wheel  14224 Oct 27  2013 g++
  8 lrwxr-xr-x   1 weston  wheel      12 Jun 30  2012 gcc-llvm -> llvm-gcc-4.2

My configs may not be 100% dev env correct, but I'm able to compile phashion fine.

How did you install Developer Tools on your machine?

Via the app store. I grabbed all of Xcode.

How did you install Ruby on your machine?

rbenv, but it's a custom ruby for work.

$ ls -l /usr/bin | grep gcc
-rwxr-xr-x   1 root   wheel     14224 Oct 25  2013 gcc
lrwxr-xr-x   1 root   wheel         5 Oct 25  2013 llvm-gcc -> clang
jch@cupcake:~$ ls -l /usr/bin | grep c++
lrwxr-xr-x   1 root   wheel         7 Oct 25  2013 c++ -> clang++
-rwxr-xr-x   1 root   wheel    434224 Oct 25  2013 c++filt
