	When in need of emergency disk space, my first trick is to
flush /usr/ports/distfiles and /usr/obj.
	If that's not enough, I empty /usr/local/lib/compat/pkg.  About
one time in twenty I discover something important was depending on a
deleted lib.  _So far_ , every time I have been able to fix this by
sym-linking lib<foo>,N to lib<foo>.N+1.
