A new (stable) version of Spam-Assassin is out, 2.31. No changes to the ebuild are necessary, just cp Mail-SpamAssassin-2.20.ebuild Mail-SpamAssassin-2.31.ebuild ebuild Mail-SpamAssassin-2.31.ebuild digest
Whoops, missed a dependancy: ">=dev-perl/Time-HiRes-01.20-r1" should be added to the DEPEND variable in the ebuild.
Added the dep.
