I'd recommend using rvm (Ruby Version Manager) to manage your different versions of Ruby and switch between them. It does a pretty good job of compiling the various versions for you too. You can even create per-directory .rvmrc files to tell rvm what version of ruby to use in which directory (as well as use per-project gem sets if you want!)
