You should be able to change its uid by deinstalling dbus, then editing
/usr/ports/devel/dbus/pkg-install, changing the uid in that script
to an unused ID, and reinstalling.

All the userids created by ports should be listed in /usr/ports/UIDs
and GIDs, so you can check to see if any other ports might conflict
with existing users.  Unfortunately, the ports themselves don't use
those files during the install, so you can't just edit that and be
done.  You have to fix each port individually.
