This is the most recent howto Haskell page: https://nixos.org/wiki/Haskell talking about how to use the Haskell packages which are packaged by official nixpkgs.
My personal solution which is an alternative called "hack-nix" allows you to install the package by adding a single line: pipesCore = exeByName { name = "pipes-core"; }; See latest commit: https://github.com/MarcWeber/nixpkgs-haskell-overlay/commit/1fde32dc7a6615a00335f33419dbc88ef84b95eb For that repository to work you also have to use the experimental/hack-nix branch found at github.com/MarcWeber/nixpkgs which adds some additional knowledge about core packages of each ghc version required by the brute force hack-nix solver. However if you use it as dependency for a different target executable its likely that running "hack-nix --build-env" will just succeed. If it does not just ping me on irc or by mail I'll write a nice wiki article now.
