I wrote it: It's called Hack-Nix and utilizies the Nix repository manager. I've added a wiki page to haskell.org some time ago.
Drawbacks: Right now it doesn't make sense to include all hackage packages because resolving dependencies would never end because its written in Nix language. I can show you how it works if you're interested.
