Dear Glynn,
Thanks for your ansewers,
I see.. so do I have to use something else than mesa or maybe to upgrading this library will fix the problem?

Right; this corresponds to a recent change.

No; AFAIK, it applies to anything using Mesa 3.x. The library defines
glXCreatePbuffer, so configure defines HAVE_PBUFFERS, so do_zoom.c
tries to use pbuffers, which fails because GLX_PBUFFER_WIDTH/HEIGHT
aren't defined in the header file.
For now, the simplest solution is to remove the line:
#define HAVE_PBUFFERS 1
from src/include/config.h.

Thanks for your ansewers,

Certainly, the OpenGL libraries/headers which are included in XFree86
4.x work. AFAICT, Mesa 4.x should also work.
Also, I've now fixed this issue in CVS.
