Build .debs either locally or (preferably) from CI, push them to an apt repository, apt-get install to production from puppet/ansible. EDIT: I should explain how this actually helps solve the problem. If I'm building a package locally, I can take advantage of all sorts of cached files which I can't assume are present on the production server. I can also use tools I don't want installed in production to speed up the process. Building a local package from cached gems is pretty quick, and will get much quicker once I've got precompiled gems sorted out. I haven't got a particularly good answer to speeding up `rake assets:precompile`, but having it fail locally is better than having it fail in production.
