title: py2app error: "can't copy '%s': doesn't exist or not a regular file"
body: <p>I'm trying to pack my Python app with py2app. I'm running the <code>setup.py</code> I created, and I get this error:</p>
  
  <pre><code>  File "C:\Python26\lib\distutils\file_util.py", line 119, in copy_file
      "can't copy '%s': doesn't exist or not a regular file" % src
  DistutilsFileError: can't copy '--dist-dir': doesn't exist or not a regular file
  
  &gt; c:\python26\lib\distutils\file_util.py(119)copy_file()
  -&gt; "can't copy '%s': doesn't exist or not a regular file" % src
  </code></pre>
  
  <p>Does anyone have any clue what I'm supposed to do?</p>
