Ryan! Long time, no see. Good to see you're joining in on the Python fun.

No good. Numeric isn't a package (in the technical sense of a collection 
of modules all in a directory that has an __init__.py, etc.).

Check for the existence of the file 
~/installed/lib/python2.2/site-packages/Numeric.pth . It should have one 
line saying, "Numeric". When the interpreter starts up, it scans what's 
in the PYTHONPATH and the defaults paths. When it encounters .pth files, 
it automatically adds the paths named in them to the PYTHONPATH.

You can also try adding ~/installed/lib/python2.2/site-packages/Numeric 
directly to your PYTHONPATH.

If you have more problems, you can contact me off-list; I'll take care 
of you.
