Any particular reason you don't want to use RVM? Avoiding rbenv or RVM is more trouble than it's worth. — Sebastian

Ruby, bundler, and gem all require a consistent set of paths and environment variables to locate the various scripts, binstubs, gemsets, and executables. RVM and rbenv have solved the problem of setting this up for each version for you. If you are determined, you can set up the environment yourself, but you'll need to learn what the authors of those version managers learned when they wrote the code. I use rbenv, and the docs do a good jobs of describing what rbenv does in maintaining a consistent environment for each installed ruby.
