"Snack" appears to be a python module provided by a package called newt, which is installed:

# rpm -qf /usr/lib/python2.3/site-packages/snack.py newt-0.51.6-9.rhel4

What am I doing wrong?

Not using python 2.3 perhaps?

Good call, looks like python is 2.5 (although the typical 2.3 package is installed). Probably, someone else using this machine needed 2.5 at some point.

Let's say we still have a good reason to need python 2.5. Is this going to break a lot of the system-whatever commands? Are there any workarounds?

Thanks again, Matt

Yeah, the system is built heavily around python. If you still need to have a different python installed, install it as python25 or something like that.
