problem with glutKeyboardUpFunc and glutFullScreen in pyOpenGL

[soul]

I have a problem in pyOpenGL.I'm programing in Linux Fedora Core 2 and I
have installed the following
packets:

python 2.3.3-6
glut-3.7-12
glut-devel-3.7-12
PyOpenGL-2.0.1.09
OpenGLContext-2.0.0b1-1


If I use the functions glutKeyboardUpFunc , I retrieve this error:

Traceback (most recent call last):
File "plantilla.py", line 340, in ?
main()
File "plantilla.py", line 320, in main
glutKeyboardUpFunc(keyReleased)
NameError: global name 'glutKeyboardUpFunc' is not definedç

Anybody can help me?

Thanks
