Perl Noob needs help

[Richard Humphrey]

I am running SA 3.0 pre2 and I am getting the following error when 
running sa-learn. I recently upgraded from 2.63 where this was not a 
problem. Thanks for any help.

]# sa-learn --spam --mbox /var/spool/mail/catchall

What does this error mean and better yet, how can I fix it. System is 
RedHat 9 and perl-Digest-SHA1 is installed.

rpm -q perl-Digest-SHA1
perl-Digest-SHA1-2.02-1.dag
