This does not bode well for my situation, as my card is no longer
supported in the closed source ati driver. Since Gazebo used to work
when I had FC3 on this machine, there must have been a change to the
xorg radeon driver. So, I guess I need to go elsewhere for a solution.

Thanks for your help Thomas. I disabled the composite extension and the
libGL warning went away. However, this is definitely not related to my
problem as I am still getting the same errors from Gazebo.

I guess I have to file a bug report with the developers of the radeon
driver and see it they can sort this out.

However, I don't have any problems running glxgears, which should give
me an error as well right? Does anyone know why this is the case? or a
way to test what is causing the problem for Gazebo? Maybe it's an
intermediary problem, like something in how GLUT uses GL/GLU?

Thanks,
Josh
