title: Global paster command not found in virtualenv
body: <p>I created a custom paster command as described in <a href="http://pythonpaste.org/script/developer.html#what-do-commands-look-like" rel="noreferrer">http://pythonpaste.org/script/developer.html#what-do-commands-look-like</a>. In my setup.py I have defined the entry point like this:</p>
  
  <pre><code>entry_points={
    'paste.global_paster_command' : [
      'xxx_new = xxxconf.main:NewXxx'
    ]
  }
  </code></pre>
  
  <p>I'm inside an activated virtualenv and have installed my package via</p>
  
  <pre><code>python setup.py develop
  </code></pre>
  
  <p>If I run <code>paster</code> while inside my package folder, I see my custom command and I can run it via <code>paster xxx ...</code>. But if I leave my package folder <code>paster</code> does not display my command anymore. I checked <code>which paster</code> and it's the version of my virtualenv. I also started a python interpreter and imported <code>xxxconf</code> and it works fine.</p>
  
  <p>I have no idea why my global command is not recognized when I'm outside my package folder!?</p>
