title: Building Rails 3 Engine Throwing Gem::Package::TooLongFileName Error
body: <p>I'm trying to build my engine using <code>gem build myengine</code> but I keep getting the following error:</p>
  
  <pre><code>ERROR:  While executing gem ... (Gem::Package::TooLongFileName)
      Gem::Package::TooLongFileName
  </code></pre>
  
  <p>I wouldn't expect <code>myengine</code> not to be too long of a name. Any idea what might be going on here?</p>
