Damn. What a nightmare.

Eric, I'm going to make some assumptions. Please forgive me if I'm off
base:

1. You're pretty new to Linux
2. You've had some prior experience with Microsoft's operating systems

None of your problems were caused by Linux, Python, MySQLdb or Zope, but
rather by your lack of familiarity with your OS. Hopefully, your three
weeks in hell have taught you that it's time to spend some time
getting to know Linux better. ;-)

As a rule of thumb, you should never need to reformat your hard
drive(!), nor reinstall Linux or Python. I repeat ... never! Too often,
users of Win95/98/NT find themselves taking this kind of course, like
when their DLLs get FUBAR'd, but that's almost never necessary with
Linux. If you find yourself thinking you need to do this, stop. It's a
sign you need to get some more information about what's happening.

Everything you'll ever need to know about Linux is available for free on
the Internet, but it can be hard to locate. So I strongly urge you to go
out and purchase a good reference book. Matt Welsh's _Running Linux_
will do fine.

Once you get your book, you want to do some reading about ldconfig,
ld.so.conf, and LD_LIBRARY_PATH.
