Hello Denis,

I have no Mac myself, but let me ask for understanding the problem.

I assume that you mean Jon Kleiser's library in "gl.tgz", right? This is
currently the only way to get openGl on pil32.

Another possibility might be running the pil64 emulator on the Mac.
Should be built automatically if you 'make' in the src64 directory. In
pil64 you can use "lib/openGl.l", but unfortunately the emulator is much
slower than native executables.

So this is what I don't understand. What exactly is the problem?
