The tarball has been re-rolled. The changes are pretty very small. They have
bump the version.h from 1.02 (4798) to 1.02 (4809), fix .desktop file, and
update the build tools.
autoconf 2.59 -> 2.61
automake 1.9.6 -> 1.10
intltool 0.35.0 -> 0.36.2
It's not much. The fix .desktop and version.h are the reason that they
re-rolled the tarball, so bump the PORTREVISION.
