Ah... dependency hell.

My favorite solution to this problem was the makedeps/testdeps approach
I saw in one of my favorite packages, but I don't remember which one it
was...

While I'm babbling on, though, I'd like to see some more commentary
concerning on-machine upgrades, and specifically, what effort there has
been made to make backing out such updates easier if they fail without
having to have a second machine.
