Ugh, yet another variable.
But I guess that one's really what people are crying for, so... :]

No doubt the possibility to do so is a good thing - but I wonder what the
results of that are. Where do we expect lesstif to be installed -
LOCALBASE or X11BASE? Does this matter?

Good thing - should have been done all the time...!

Hum - do we use PREFIX then at all? Or just steer clear of it, and, use
LOCALBASE everywhere, and just use X11BASE when we need to get to X stuff?
Sounds so to me...

The latter's what's already in bsd.pkg.mk (but not in pkg_add) to stop
things happening if there's no X installed.

If I understand things right so far, the only thing USE_X11 is left to do
after  all these changes is to switch to the X mtree file. Maybe we should
make this only for USE_X11BASE and nuke off USE_X11 altogether?
