Run VPython on FC3

[York]

Hi everybody,

I am trying to run VPython on FC3. The installation was fine. But when I 
"import visual", an error occurs:

"""
 >>> import visual
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
   File "/usr/lib/python2.3/site-packages/visual/__init__.py", line 15, in ?
     import array_backend
   File "/usr/lib/python2.3/site-packages/visual/array_backend.py", line 
1, in ?
     import cvisual
ImportError: libgtkgl.so.4: cannot open shared object file: No such file 
or directory
 >>>
"""

It seems Python cannot open/find the file "libgtkgl.so.4", but it 
definitely lies in the lib directory:

/usr/local/lib/libgtkgl.so.4.0.0
/usr/local/lib/libgtkgl.so.4

Does anybody know a solution for this problem?

Thanks very much,

York
