I've experienced this on Debian, but it was Debian's fault, not NVIDIA.
Do other OpenGL binaries work such as Quake 3 or precompiled versions of
games such as armagetron? It very well could be a problem with your build
Additionally, the ldd output of your binary, does it contain a line
libGL.so.1.something? If not, I know exactly what the problem is. More
information is required to accurately diagnose your problem.
