We could do that by bumping the 4th component of each library, so that
that version isn't on hackage and thus cabal-install can't replace it.
I've done so for array and containers. That should fix the immediate
problems, at least.
Thanks! Of course, by now, the head no longer builds. And somehow,
that only applies to head, not to head fast.. Any suggestions as to which
patches I should remove to get it to build again?
