Unfortunately, that seems to have no impact.

Since I hadn't been replying to the whole list, you missed my reply to
Jim regarding that:

# sudo -u apache python
Python 2.4.3 (#1, May 12 2007, 21:38:42)
[GCC 3.4.6 20060404 (Red Hat 3.4.6-3)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import traceback
>>> import linecache
>>>

Everything imports fine in this case.

I'll give that a shot and report back. Thanks for the help.

Whoops, sorry about that! I'm used to lists that put the list's email
in the reply-to, so I didn't even think to check the headers before
replying.
