I don't think so. If there is a real dependency, then we want it to be
noticed. Look:
libA -> { libB, libC }
libB -> libC
Now libB is rewritten to not need libC any more (imagine it provides
low-level stuff like glib). If we do not listen to what the user tells
us, we end up with a broken installed library libA.

Erm, is this not handled in the depending library? (I have no idea,
really, but I hoped this would be so.)

Me neither.
