[Nix-dev] Updating haskell packages to ghc 6.12.2?

[Jason Dusek]

  Where is GHC 6.12.2 availabe for NixOS? I have the 'unstable'
  package collection:

    http://nixos.org/releases/nixpkgs/channels/nixpkgs-unstable/

  and only that channel but seemingly no 6.12:

 :; nix-env -qa '*' | egrep 'ghc6\.12'

  I updated my channel just now.
