That's pretty cool. I was thinking of bundling a default.nix in the root of my projects with maybe a recipes/ folder for things like ruby, libxml2, ... It's definitely possible to do that and even link to nixpkgs but then your projects dependencies might break each time you updated nixpkgs. I don't know of a nice way to solve that. My sample looked something like that: let pkgs = import <nixpkgs> {}; stdenv = pkgs.stdenv; in stdenv.mkDerivation { name = "my_project"; src = ./.; ... There's also a deps.mix for just the dependencies. It's on an internal project so I can't really divulge the details but email me if you want to talk more about it.
