Hmm, I'm running Mesa 6.5.2 on my Gentoo machine (with the nvidia 
driver) and am not seeing errors with the original code.  I've replaced 
the calls in _afterCheck with the glGetShaderiv and glGetProgramiv 
calls.  Is there a reference somewhere that describes why the 
glGetObjectParameter calls are wrong, and in which cases they should be 
used?

Thanks,
Mike
