.so files not updated correctly?

[Rishabh Malviya]

I had forked this repository and noticed something weird happening when compiling my changes.

I would make changes to the source files in the root directory, and then run luarocks make loadcaffe-1.0-0.rockspec. It seems everything would be updated correctly in my install location (~/torch/install/), except for the libloadcaffe.so file; because of this, I was copying the generated libloadcaffe.so file in my build directory to the install location manually.

I verified this by comparing the MD5Sums listed in the installed rock-manifest file (~/torch/install/lib/luarocks/rocks/loadcaffe/1.0-0/rock-manifest) with those of the generated files in the root directory, as well the files actually installed in the install locations both before and after running luarocks make:

As you can see, both libloadcaffe.so and the source .lua files are updated, but the md5sum of the libloadcaffe.so in the source directory does not match that of the files in the rock-manifest and at the install location.
