title: How do I point RVM to my Homebrew Ruby dir?
body: <p>I installed Ruby 1.9.2 using homebrew, then installed RVM. </p>
  
  <p>I want to point RVM to the version I have in my Cellar folder. How can I make <code>rvm --default 1.9.1</code> point to the one in Cellar without having to reinstall it again using RVM?</p>
