title: How to install gcc-4.2
body: <p>I am trying to update ruby and rails on my system (osx 10.8.2)</p>
  
  <p>When I run </p>
  
  <pre><code>rvm install 1.9.3 --with-gcc=gcc-4.2
  </code></pre>
  
  <p>I get the following error:</p>
  
  <pre><code>You requested building with 'gcc-4.2' but it is not in your path.
  </code></pre>
  
  <p>2 questions; how do I install using gcc-4.2 (I have installed command line tools in xcode)?
  Also, How do I get it to the correct path?</p>
  
  <p>Any help in this issue would be greatly appreciated.</p>
