All I can say is that the way pkgsrc iteslf does this now (by not
registering the installed package) is completely bogus.

Until pkg_install acquires some better way to deal with obsoleted files
(i.e. other than hacks possible now with INSTALL scripts and whatnot)
there's no way to do proper "updates" of packages -- only removes and
Ideally package updates should be easily revertable too -- especially if
the update breaks half way through. Such a revert operation might have
to be done by hand for some packages of course....
