I suggest you redirect to the archives from
http://mail.python.org/pipermail/python-list/.

Seems relevant:
https://code.google.com/p/pyglet/issues/detail?id=615&colspec=ID%20Stars%20StatusType%20OpSys%20Modified%20Summary


If
https://code.google.com/p/pyglet/issues/detail?id=630&colspec=ID%20Stars%20StatusType%20OpSys%20Modified%20Summary
is
your problem then, for me:

>>> import pyglet
>>> pyglet.window
<pyglet._ModuleProxy object at 0x7ffab02cf690>
>>> pyglet.window.Window()
<pyglet.window.xlib.XlibWindow object at 0x7ffab02c7b50>

Window pops up.
It works! Sorry.

What happens when you help(pyglet) and help(pyglet.window) and
help(pyglet.window.Window)?
