title: Disable RVM or use Ruby which was installed without RVM?
body: <p>For rails application I had installed Ruby 1.8.7 and Rails 2.3.11. And it was working fine. After that I have installed RVM and REE. 
  So while running ruby script/server it's using REE. But now I want to use the older Ruby 1.8.7 which was installed without RVM.</p>
  
  <p>Any Solution!</p>
