Thanks for this. I used to use ruby a lot - mostly just because it's the nicest language for scripting things on unix. I can remember trying to get it set up a year or so ago and finding the process difficult (think I was using rvm). https://github.com/rbenv/ruby-build/wiki#suggested-build-environment https://github.com/rbenv/ruby-build/wiki#suggested-build-env... probably good idea to point people here before they install ruby, since it'll compile for minutes then tell you it's missing a dependency, and you have to start the whole process over.
