I'm glad to hear that the infrastructure is working for you. There are, admittedly, some kinks on master, though I have a PR to make things much, much more robust: https://github.com/NixOS/nixpkgs/pull/8612 https://github.com/NixOS/nixpkgs/pull/8612 Unfortunately, while Bundler is generally a great, useful piece of software, there are aspects of its design that make it very difficult - borderline antithetical - to cooperate with packaging; if you look at the commit message in the above PR, you can see a thorough description of the challenges. I have an open PR for Bundler to try to make things a bit more amenable, and recently got the thumbs up with respect to the general idea: https://github.com/bundler/bundler/pull/3775 https://github.com/bundler/bundler/pull/3775 Unfortunately, most Ruby deployments are quite imperative in nature - just push to a git repository, bundle install, and then bundle exec (that's leaving out all of the subtle prereqs: `apt-get install ...`, etc), as with Capistrano. There doesn't appear to be as much of a culture around packaging (yet), and so there hasn't been a demand for the tools to meet those needs. I hope that we can push through those problems and make it trivial for people to enjoy the ease/dependability/resiliency of package management, as many people have no idea what they're missing out on.
