Ah, I didn't make it clear that it's also the same VM! (Well, probably
a new freshly downloaded 2714.) Since neither the image nor the VM had
changed (modulo limitations of my memory), I thought perhaps the
environment had changed.

One possible next step is to just store my changes and rebuild from a
pristine image. (Easily done, given that I'm just hacking on
Installer.)
