sa-learn refuses to learn.

Hello SuSE people. Originally set up spamassassin and had it learn from my mailboxes in Kmail. worked fine. I set up a special spam mailbox with a sub-mailbox named MissedSpam in which I placed spam that was slipping through. Now I want sa-learn to check on that mailbox and learn from it. What I do is, cd into: '/home/bob/Mail' and then do a: "# sa-learn --spam --mbox -f /spam/MissedSpam" Then I get this strange message. "No such file or directory at /usr/lib/perl5/site_perl/5.8.0/Mail/SpamAssassin/CmdLearn.pm line 120." Can somebody, please, tell me what I am doing wrong here? Bob S.
