login as regular user, download some version of ruby, compile for use as logged in user, install rvm, shazzam install any version of ruby you want - all of this only applies to the logged in user and has zero impact on the rest of the system. RVM rules :) I no longer install ruby at a system level, not needed, only users running ruby stuff need ruby installed and never use distro ruby, creates all sorts of issues...
