Thanks Ben, not necessary - that's enough. I can see the same output that I can 
also see on my Mac. But I still do not understand why it should be necessary to 
#include <OpenGL/gl.h> instead of #include <GL/gl.h> on a Mac platform? I think 
we need Carlo's output of

  bash~$ sudo find / -iname gl.h

I also tried to replace the #include <GL/gl.h> with #include <OpenGL/gl.h> and 
the same for the glu.h. Next I tried the -FOpenGL flag with CPPFLAGS. All with 
the same result: a compilation error. So, might there be some mismatch of GL 
headers? BTW, I'm posting my output from my Intel 10.4.9 system (that, BTW, I 
try to keep as clean as possible):
