Re: bulk builds incompatible with changes

I don't let it rescan when running bulkbuild-restart because that's just 
not feasible on certain architectures.

So, for instance, now that Perl has changed, I see lots of failures like 
this in depends.log:

pkg_add: no pkg found for 'perl-5.40.1', sorry.
pkg_add: 1 package addition failed

Of course this is easily fixed with sed, but it really would be nice to 
have a way to cleanly scan changes without rescanning the whole of pkgsrc.
