What does "ghc-pkg list" and "ghc-pkg check" say? Cabal-1.10.1.0, directory-1.1.0.0 and process-1.0.1.5 should be there after installation of GHC 7.0.2. (I've actually installed cabal-install-0.10.0 using an older cabal, but that does not work on macs and may not be the recommended way.)
I think I've used http://www.galois.com/~dons/code/2011.2.0.0/haskell-platform-2011.2.0.0.tar.gz from http://www.galois.com/~dons/code/2011.2.0.0/, but they are not official yet. C.
