I recently upgraded my spamassassin 2.64 to 3.02 on three machines (two Solaris, one FreeBSD).
The Solaris installs went according to the upgrade notes/wiki, but the FreeBSD machine was a bit different, in that It required the "Storable" module from CPAN. once I installed it, it went smooth. just FYI. -- Jeremy Kister http://jeremy.kister.net/
