[Visualpython-users] 10.04 installation problem

Hello,

I've been refreshing computers in my teaching lab, and I've hit a bit of a snag that has me stumped. On a fresh install of Ubuntu 10.04LTS, installing vpython is as easy as 
	sudo apt-get install python-visual
and IT WORKS!

However, when I try installing the same Ubuntu 10.04LTS under Parallels Desktop on my Mac, the same apt-get seems to work, but then when I import visual and try something like x=sphere() I get this:

VPython ***CRITICAL ERROR***: /build/buildd/python-visual-5.12/./src/gtk2/render_surface.cpp:88: render_surface: failed to initialize any OpenGL configuration, Aborting.

I have exhausted my expertise on this one. I don't think it's a package issue, as I've done this:
	dpkg -l > virtual	# on the VM that does not work
	dpkg -l > native	# on the non-VM that works
	diff virtual native	# shows no differences

If anyone has any suggestions, I'd love to hear them. I'm at a complete loss on this one.
