A mass revbump only solves the problem for those people tracking pkgsrc-HEAD
and NetBSD-current at the same time (and in the right order). People who are
using 5.0_BETA or older now and upgrade to current (or 6.0) later, while
having updated their pkgsrc in the meanwhile (most likely), will still face
the problem. For them the mass revision bumping in pkgsrc will only be an
extra annoyance in the meanwhile.
Can't we just yell loudly in UPDATING, on current-users and in the 6.0 release
