Well - we install the rules that are provided by upstream. I guess this bug should go upstream instead.
Reported upstream: http://issues.apache.org/SpamAssassin/show_bug.cgi?id=5454; as far as I can see (being a Perl illiterate) the problem is with the rules coming from the update channel, so there's nothing that can be done on Gentoo side. I'd suggest a RESOLVED UPSTREAM.
