I've built GHC 7.04-4 from Debian unstable and the rest of the packages of which haskell-platform depends in a PPA: https://launchpad.net/~serras/+archive/ghc-from-debian-unstable This makes impossible to use the rest of libghc-* libraries already packaged in Ubuntu, but the developer may use "cabal install" to get them in the system.
