It's not an absolute requirement. Just like keeping world and kernel
in sync, it's really only an issue if you have updated your source
code.

The original problem was such a dependency headache.

Definately not.

Perhaps the handbook should be a little more clear about dependency
problems. Maybe a section on what to do with buildworld problems:
# rm -rf /usr/obj/usr
# cd /usr/src; make cleandir && make cleandir
# make buildworld <your options here>
And if it fails again, _then_ mail -stable or -questions.
