homebrew 2.3 install on RedHat9 not playing nice with Tkinter

[Rob Andrews]

I'm on a Red Hat 9 system, which has Python 2.2.2 installed, and I installed
2.3 separately into /home/rob/Python-2.3/ (creating the symbolic link
"py23" to point to my 2.3 installation). Now I'm trying to work out the
kinks in the process.

Unable to run Idle using 2.3 the way I've got things set up, I created a
super simple Tkinter test program that just pops up a Label widget. I
pasted below an example of how the RH-provided 2.2 runs the script without
incident, but running the script with 2.3 produces a traceback. If someone
can help me see the error of my ways, I'll be most appreciative.
