Yeah, I saw this with arp-scan too. Anyone else seeing similar issues, if you need a fix right away:- rebuild relevant packages (either the affected port itself or some library dependency). If you can't figure it out, wait for a new package snapshot, I have bumped REVISION for everything which I think needs it so that when you "pkg_add -u" against newly built packages you'll pick up the rebuilt versions.
