When you have a problem like this with one install looking one place
and another install looking in another place making a symbolic link is
usually easier and more likely to catch everything than making a copy.
In your case you could have said:
ln -s
/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages
/Library/Python/2.5/site-packages
I'm glad you quickly found the root cause.
