title: Unable to gather python interpreter info for pydev
body: <p>OS: Windows 7 x64</p>
  
  <p>Python: 2.7.3</p>
  
  <p>Pydev: 2.7.1.2012100913</p>
  
  <p>Eclipse: Version: Juno Service Release 1  Build id: 20121004-1855</p>
  
  <p>I am unable to configure a python interpreter in Pydev. If I try using the auto-configuration or the manual configuration I get the same type of error output:</p>
  
  <blockquote>
    <p>Unable to gather the needed info from the system.</p>
    
    <p>This usually means that your interpreter is not in the system PATH. No
    output was in the standard output when trying to create the
    interpreter info. The error output contains:>>&lt;&lt;</p>
  </blockquote>
  
  <p>or</p>
  
  <blockquote>
    <p>See error log for details. No output was in the standard output when
    trying to create the interpreter info. The error output contains:>>&lt;&lt;</p>
  </blockquote>
  
  <p>Python is in my PATH. Here is the output of <code>interpreterInfo.py</code> (stdout and stderr):</p>
