Have you tried initializing PyOpenGL first?

When I try running those two lines of code on a machine that I know has 
the frame buffer object extension, without initial PyOpenGL first, I get 
the same error message.

In general, I would recommend using the frame buffer object extension 
for off-screen rendering. There are older techniques like p-buffers, but 
they're more difficult to use. One downside of frame buffer objects is 
that some older/cheaper graphics chipset drivers do not support them.
