I have installed mailman-2.1.5 (from source on a debian) but keep getting the below error messages from cron. The jobs are scheduled in the crontab for the "mailman" user.

check_perms reports "no problems found"

I can run the scripts just fine, without getting any error output, if I do it manually as the mailman user from the shell: /usr/bin/python -S /usr/local/mailman-2.1.5/cron/checkdbs

Also, as the mailman user, I have no problems with creating/writing to the files and dirs that apparently have wrong permissions (according to the cron mail).

How can I get rid of these annoying error messages?
