Bootstrap with RVM

rvm –create –rvmrc use <ruby>@<gemset>

RVM will create a .rvmrc for you which will check that your project’s ruby and gemset are properly installed and if not, it’ll install them.  Plus as a bonus, if you have a Gemfile (i.e. you’re using bundler), it’ll check for that, install if necessary, and run a bundle for you in case you’re missing any gems.
