title: Textmate does not run ruby with the latest version
body: <p>I have updated my ruby to 1.9.3.</p>
  
  <p>However, when I run my ruby code in Textmate, it still run with 1.8.7 version.</p>
  
  <p>To be more specific, here is my test code, just one line:</p>
  
  <pre><code>#!/usr/bin/env ruby -v
  </code></pre>
  
  <p>when running in Textmate (command + R), the result is:</p>
  
  <pre><code>ruby 1.8.7 (2012-02-08 patchlevel 358) [universal-darwin12.0]
  </code></pre>
  
  <p>when running in the command line (./test.rb), the result is:</p>
  
  <pre><code>ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-darwin12.0.0]
  </code></pre>
  
  <p>so how to edit my Textmate to support the newest ruby?</p>
