There was no functional changes, just a minor cleanup of the configure script. (Thus I kept PORTREVISION unbumped) Hereby welcome the distfile to MASTER_SITE_LOCAL, the Hall of Shame. (The author promised me he wouldn't do that again, though ;)
(I'll suggest the author to bump the version number next time, instead of repacking ;)
The patch has been sent to the author and will hopefully be merged soon. I am adding it as a distribution patch to avoid the repo bloat.
