invoking Gl.is_available? crashes irb
I'm running ruby 1.9.3 installed from rvm on a mac running OS X 10.6.8.
Here's the dump from irb of the interaction I performed to make it crash. It's certainly reproducible on my system. I haven't tried to reproduce it on other machines.
If you contact me, I'd be happy to help diagnose the problem further.

Abort trap $
Error is at glGetString(GL_EXTENSIONS); in ext/gl/gl.c. Still dunno how to fix it (glGetString is an OpenGL function).
