[PyOpenGL-Users] GLUT import error

[<lit...@gm...>]

I have installed PyOpenGL-3.0.0a6 in Python2.5 by using "python
setup.py install". However, when I was using it:
>>> import OpenGL.GLUT
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "d:\python25\lib\site-packages\pil\__init__.py", line 4, in <module>
    #
  File "build\bdist.win32\egg\OpenGL\GLUT\special.py", line 73, in <module>
AttributeError: 'NoneType' object has no attribute 'glutDestroyWindow'

Is this a bug? What should I do for correctly importing GLUT?
Thank you.
