Ok, I did a little research to verify this.  The only place the
"regsub" or "regex" modules are used are in Bouncers/Catchall.py.
Further more, the only place Catchall is used is
Bouncers/BouncerAPI.py.  And finally, the only places BouncerAPI is
used is cron/qrunner.  Thus qrunner is dependent on regex, but it is
also the only place requiring regex.

It does indeed seem that "regex" is required for qrunner to work, and
hence Mailman.  Is it very unusual not to have "regex"?  Is RH 7.2
Python > 1.5 essentially broken?  FWIW, I've checked RH 7.3.  It ships
with Python 2.2 and 2.0.  Both have "regex" built in.
