Conflicts: gobby and libinfinity - I took the hand-edited versions
instead of those resuting from the mass-replacement.

no redundant dependencies the library component of `scientific-0.3.5.1` depends
on `ghc-prim` which is unused in the library.
### Using hackage2nix with nixpkgs
Hackage package derivations are found in the
[`hackage-packages.nix`](https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/haskell-modules/hackage-packages.nix)
file within `nixpkgs` and are used as the initial package set for
`haskellPackages`. The `hackage-packages.nix` file is not meant to be edited
by hand, but rather autogenerated by [`hackage2nix`](https://github.com/NixOS/cabal2nix/tree/master/hackage2nix),
which by default uses the [`configuration-hackage2nix.yaml`](https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/haskell-modules/configuration-hackage2nix.yaml)
file to generate all the derivations.
To modify the contents `configuration-hackage2nix.yaml`, follow the
instructions on [`hackage2nix`](https://github.com/NixOS/cabal2nix/tree/master/hackage2nix).
