Yes, and that it contains PACK-VER/PACK.cabal.  That's what "setup sdist"
makes, and it is checked on upload.

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.
