Cron jobs do not have the standard path when they run.  Odds are the
module (or something it calls) can't be found on cron's limited
path.  This can be fixed by putting a

	PATH=$PATH:/path1[:/path2]

(where /path1, etc. are the paths you want to include in the search)
after the "#!/bin/bash" at the top of the /etc/cron.daily/0logwatch
file to expand the path that cron has.  That, or make sure you use an
absolute path (e.g. "/usr/bin/name-of-program") for each program you're
running in the crontab.
