[Mailman-Users] ImportError with regex and binascii? List has stopped sending

[Gee]

This is another one of those "now why my list has suddenly stopped 
working"  questions.

I got everything working last night. Sent some test messages. Everything 
worked OK until sometime this afternoon; now messages sent to any of my 
lists disappear into Tumbolia without a notice.

I've double checked my crontab, and made sure that crond is running, so I 
don't think that's the issue. A few data points that may be relevant...

-- Getting this beast to run was a bear 'cause RedHat 7 apparently does not 
cooperate with the #! /usr/bin/env python shebang in the scripts. I kept 
getting an error during configure that Python could not be found. I changed 
all the Python scripts to !#/usr/bin/python2.1 and things worked seemingly 
without error. Mailman installed. Lists were made. Messages were sent 
succesfully. The whole works.

-- When I noticed messages aren't going through, I checked the 
/home/mailman/logs/error file. It is rife with ImportErrors.

One began last night and has been repeating since:

...plus, as you cans see, there's something going on about a corrupt archive.

The other started this afternoon and has been occurring since:

Apr 16 16:34:02 2002 qrunner(5706): ImportError :  No module named regex

I double check the Pythong directory (/usr/lib/python2.1/) and there, 
indeed, is not regex module there. But the notes in the modules imply that 
there has been some sort of workaround (maybe? I have no experience with 
Python outside of this Mailman install)?

I am assuming that Mailman can indeed play well with Red Hat, but I am at a 
loss of what to do next. Big thanks in advance for any guidance.
