For a slightly different setup (with the jekyll-assets plugin, and
nodejs as external dependency), I am using a Gemfile, bundix, and
nix-shell.

Gemfile:

  source 'https://rubygems.org'
  gem 'jekyll'
  gem 'jekyll-assets'

shell.nix:

  with (import <nixpkgs> {});

  (bundlerEnv {
    name = "cookbook";
    gemset = ./gemset.nix;
    gemfile = ./Gemfile;
    lockfile = ./Gemfile.lock;
    buildInputs = with pkgs; [ nodejs ];
  }).env

If I remember, all you have to do then is:

   bundler lock
   bundix expr
   nix-shell

Gabriel.
