title: Can't install Ruby Enterprise Edition with RVM on OSX Lion
body: <p>Here is what I have done so far. </p>
  
  <ol>
  <li>Clean install of OS X Lion</li>
  <li>Downloaded and installed latest version of Xcode from the App Store. </li>
  <li>Installed Git</li>
  <li>Installed Homebrew</li>
  <li>Installed RVM</li>
  </ol>
  
  <p>I am now trying to install Ruby Enterprise Edition for a project with <code>rvm install ree</code> and receive the following error: </p>
  
  <pre class="lang-none prettyprint-override"><code>$ rvm install ree
  ree-1.8.7-2011.03 - #installing
  ERROR: Error running './installer -a /Users/FaraazKhan/.rvm/rubies/ree-1.8.7-2011.03
    --no-tcmalloc --dont-install-useful-gems ', please read
    /Users/FaraazKhan/.rvm/log/ree-1.8.7-2011.03/install.log
  ERROR: There has been an error while trying to run the ree installer. Halting
    the installation.
  </code></pre>
  
  <p>I have already tried <code>CC=/usr/bin/gcc-4.2 rvm install ree</code> and with the same result. </p>
