[Mailman-Users] Cannot read wrapper configuration file error - please help!

[brandon dudley]

For some reason, my mailman installation stopped working on Sunday, 
giving the typical "got GID xx" message. Because I had installed
mailman from rpm, I decided to reinstall it from the same rpm. When I
did this, and fixed the alias file, any post to any of my lists gives
the above error message. I did a search of the archives and saw this
question appear from time to time, but there was never an answer
given.

OS: SUSE 9.1 (i386)
version: mailman-2.1.4-83.3 (SUSE's numbering)

run manually:
mailman at misanthrope:/usr/lib/mailman/scripts> /usr/lib/mailman/mail/mailman post
Cannot read wrapper configuration file.

logged error msg:

/var/log/mail.warn:Oct  5 12:59:01 misanthrope Mailman mail-wrapper:
Cannot read wrapper configuration file.

/var/log/mail.info:Oct  5 13:02:34 misanthrope postfix/local[18980]:

(Command died with status 8: "/usr/lib/mailman/mail/mailman post xxx".
Command output: Cannot read wrapper configuration file. )

thanks in advance, and fingers crossed!
