title: Python virtualenv -> New python executable in venv/bin/python
body: <p>I'm currently trying to install Sevabot with this tutorial: <a href="https://sevabot-skype-bot.readthedocs.org/en/latest/ubuntu.html" rel="nofollow">https://sevabot-skype-bot.readthedocs.org/en/latest/ubuntu.html</a> Everything is going fine until I need to install Sevabot. I can download the virtualenv.py file just fine but when I want to execute python virtualenv.py it returns a error.</p>
  
  <blockquote>
    <p><code>~/sevabot$ python virtualenv.py venv
    New python executable in venv/bin/python
    Cannot find sdist setuptools-*.tar.gz
    Cannot find sdist pip-*.tar.gz
    </code></p>

  <p>Weird thing is, I have done this 5 times without any problems. Always Ubuntu 12.04 x86_64. Already did a clean install several times.</p>
