That's talking about the sources of a release, from a page like
http://www.haskell.org/ghc/download_ghc_682.html

These are darcs source snapshots. The filenames are

ghc-HEAD-2007-12-16-ghc-corelibs-testsuite.tar.bz2
ghc-HEAD-2007-12-16-ghc-corelibs.tar.bz2
ghc-HEAD-2007-12-16-ghc.tar.bz2

The first includes all of the second, which in turn includes all of the
third.

No, you only want one of them - probably the first one.
I don't think it includes the most recent library split, so you'll need
to ./darcs-all get after untarring it.


Thanks
