Dave,
  Try adding this to the top of OpenGLExtensions.C (before the include lines):
#define GLX_GLXEXT_PROTOTYPES 1

I'll have to see what's in the latest version of the NVidia headers versus
the official ARB headers, in theory this shouldn't be necessary, but there
are many variations of those headers unfortunately.

Thanks,
  John Stone
