Can one safely assume that
http://hackage.haskell.org/packages/archive/PACK/PACK-VER.tar.gz
untars into a PACK-VER directory containing that package?
Yes, and that it contains PACK-VER/PACK.cabal. That's what "setup sdist" makes, and it is checked on upload.
Earlier you've mentioned some sharing of libraries. Could you elaborate a bit how this should work in detail? I only have a very vague idea, and I am not sure if this is a must or only a nice-to-have.
I'd find having copies of the source trees a bit awkward, so I use a custom setup with shadow build trees. Since GHC wants to manage the darcs trees, I link to those. Maybe it's just a nice-to-have, and things may change when GHC becomes more independent of most of the libraries.
