That may very well be the case, but if so then it's incumbent on portmgr 
to communicate that. If you check the audit trail you will find that 
they did not.

IMO this is a total red herring, and has been for several years now. I 
run -current every day on my real-work system, and barring the 
occasional hiccup it's been buildable nearly every time I've tried.

The way I would approach the problem of building packages for -current 
is to pick a day to update the src tree, then do the following:

1. make buildworld && make kernel && reboot &&
2. make installworld && reboot &&
3. update ports tree &&
4. start building ports

That can all be automated, and at the point where any of it fails the 
system barks loudly and stops trying to proceed. This would of course 
require a human to be involved once a week or so with running 
mergemaster, and maybe the odd cleanup here or there, but most times 
that doesn't even have to happen in band. I suggest Wednesday as "the 
day" to update the source since there is usually a lot of activity on 
the weekend, and if something is broken on Wednesday it gives people a 
chance to respond during working hours.

The great thing about this is that if it fails, no harm no foul. Having 
some packages, even a week or so out of date is much better than what we 
have now.

Of course, there are other things that would go along with this ... 
finding and tagging the very few packages that actually deeply care 
about system internals being first on the "off the top of my head" list. 
But the current system of "don't do anything" just isn't cutting it.

If portmgr is unwilling/unable to do the exp-run before dim is ready to 
commit, then I'd say yes, that all sounds fine; especially bumping 
__FreeBSD_version.
