Do you have any non-Mesa libGL libraries on your system?

My guess is that you're not linking with Mesa's libGL.  Try adding a -L
option to your gcc command to point to Mesa's libGL directory.

You can't use NVIDIA's libGL, nor the XFree86/DRI libGL with this widget.

I generally recommend using the standard, SGI widget in Mesa/widgets-sgi/
since it uses the standard GLX interface.
