title: I can't get MXMLC to work on Ubuntu
body: <p>Okay, I downloaded the Flex 4 SDK from Adobe and extracted the contents to <code>~/Documents/flex4_sdk</code>.</p>
  
  <p>Now I have the following simple MXML file:</p>
  
  <pre><code>&lt;?xml version="1.0"?&gt;
  &lt;!-- usingas/StatementSyntax.mxml --&gt;
  &lt;mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"&gt;
  
      &lt;mx:Label id="label1"/&gt;
  
  &lt;/mx:Application&gt;
  </code></pre>
  
  <p>When I compile it with <code>mxmlc /path/to/file.mxml</code>, I get:</p>
  
  <blockquote>
    <p>Loading configuration file ~/Documents/flex4_sdk/frameworks/flex-config.xml<br>
    /path/to/file.mxml (38642 bytes)</p>
  </blockquote>
  
  <p>However, the resultant SWF file is blank. (Basically just a white canvas.)</p>
