Unless glut's context and the pbuffer's context are shared, I believe
that you have to make the pbuffer's context current when you create the
shader. (I haven't had any luck getting glut to share its context with
a float pbuffer, but admittedly, I haven't tried very hard.)
ie:
CGLSetCurrentContext( pbuffer_cxt )
// create pbuffer shader here
CGLSetCurrentContext( glut_cxt );
// create glut shader here
This is what I'm doing with ARB shaders that operate on floating pbuffers.
