I'm not able to install the recent 1.2 version, only legacy versions which are not usable.
Add own nixpkg, follow: https://nixos.org/manual/nixpkgs/stable/#developing-with-ruby Write a custom Gemfile including the sitediff gem. Generate lock and gemset via `nix shell nixpkgs#ruby nixpkgs#bundix` and the documented commands.
