Just make sure it's Artistic License v2; there are some doubts over v1 and while most of the perl community doesn't really seem to be worried by them certain distros (notably fedora) dislike it and tend to spam people with software under it asking them to relicense.
Me, I just use the perl5 license and tell the people who don't like AL1 they can use the GPL half of the disjunction if it upsets them so much.
