Hello Alexander,

Yes, I installed pil32 and Jon Kleiser's library. I built everything but the 
small test program could not find the gl functions wrappers.

So I modified the gl lib makefile and everything works : now I have a pil32 
running with openGL on mac os 10.6 (so not need for the emulator).

BUT:

1) The changes I made are surely not perfect, they are likely to cause some 
troubles on the other OSs or other (older?) versions of mac os x. So I have 
just explained them here, because they could be useful for another user or to 
correctly fix the makefile (sorry I cannot help more).

2) I have been curious to understand how to link pil32 with C code, so I had a 
look at the gcc.l file and the Darwin section might not run on a 64 bits mac, 
because it uses the same arguments for gcc as the gl makefile. 

So, no problem on my side, but it would be nice if someone else could issue a 
proper fix (unless the real 64 bits for mac osx will be soon available).

Thanks,

Denis
