Install RVM, make it part of your shell, then install the ruby and gems 
of your choice. That way you leave the system Ruby alone and can develop 
with the versions you want. You can even do multiple versions of ruby 
and various gems for working on many different projects at once.

	It really is the simplest way to build a dev environment and maintain 
it for Ruby.
