[Visualpython-users] can't run any VPython programs

Hi.
I'm using Mac OS 10.2.3, Apple's implementation of X11 
<http://www.apple.com/x11/> based on XFree 4.2.1, Apple's X11 SDK, Fink 
0.5.1, and Visual-2002-07-22 from the VPython web site. Everything 
installed properly with no errors. I forgot to become root to run the 
VPython install script, but I ran it again as root. Actually, I ran it 
again with "sudo" which worked under OS 10.1.5 and Fink 0.4.1.

Now, when I try to run any VPython program from IDLE, here's what I get:

-----begin error message
Visual-2002-07-22
Traceback (innermost last)
   File "/sw/share/python-visual/Programs/Demos/orbit.py", line 1, in ?
     from visual import *
ImportError: Failure linking new module

Program disconnected.
-----end error message

This specific example was for orbit.py, but I get the same error with 
any program, and I get the same error whether I run the program from 
the ~/VPython/Programs/Demos folder or from the duplicate folder under 
/sw.

Any suggestions?

Joe
