Well, .pyc files may have absolute paths in them, and don't always work 
if you move them to different directories.  You need to get Zope itself 
working with Python 2.2 (if that is the version of xsv you have).  Then 
you need to get the xsv packages into the Python path (I like to use 
.pth files, and you have to make sure they are in Zope's Python path - 
it is not uncommon to think that the Python path is set right, but it 
turns out to be the path of some other Pyton installation instead of 

I would then delete any .pyc or .pyo files that may be in the xsv 
directories.   Then restart Zope.

You could load Zope's Python 2.2 interpreter from the command line and 
make sure that it can import the right xsv packages.  At this point, 
your external method should be able to load your code.
