When pyglet creates a window it tries to bind a shared GL context, and in
your case fails.
Seems that sharing contexts are not working in your system.
Thats usually a harware / driver limitation, by example the old intel 945G
integrated graphic chipset does that with certain driver versions.
Your best bet is to try updating drivers; sadly some old laptops don't
upgrade the branded drivers, and don't allow to use the generic drivers.
As a dirty workaround you can add at the very beginning of your program
import pyglet
pyglet.options['shadow_window'] = False
For further advice, I suggest to run some of the pyglet samples and report
the traceback to pyglet mailing list, adding info about your video chipset
