Whenever you need to have couple of rails env RVM is always a good idea.

If you only wish to install rails 2, then specify the version you want when installing the gem

gem install rails-2.3.5

If you want to maintain different versions of rails, then you probably also want to maintain different versions of ruby. In that case, rvm is your friend.
