Problems installing via OPAM on OSX

[tmcgilchrist]

I tried installing via OPAM and I get the following error which looks like some of the deps aren't met on the latest OSX version. Possibly it's not finding the X11 libraries it expects.

➜  ~  opam install glMLite 
The following actions will be performed:
 - install glMLite.0.03.51

From this error message: "fatal error: 'jpeglib.h' file not found" it seems that the header files for the jpeg lib are not found in the searched path.

If you don't need the jpeg file loader you can compile only the base module: "GL".

For people that will have the same problem :

You can compile by setting

export C_INCLUDE_PATH=/folder/to/jpeglib.h

You will maybe then have an error saying that it does not find -ljpeg :

export LIBRARY_PATH=/folder/to/libjpeg.dylib

I tried to set DYLD_LIBRARY_PATH multiple times without success. LIBRARY_PATH made it work. Compilation should just work fine now.
