title: Virtualenv cannot find my application
body: <p>I've been developing an application mainly on my Mac, and now I'm trying to
  setup the development environment on a Windows box. The application files are in
  place so I started with virtualenv, which installed just fine:</p>
  
  <pre><code>&lt;extracted virtualenv-1.10.1.tar.gz&gt;
  cd virtualenv-1.10.1
  C:\Python27\python.exe setup.py install
  </code></pre>
  
  <p>I navigated to my application dev folder and ran the develop command:</p>
  
  <pre><code>(env) C:\Users\eclaird\work\MyApplication&gt;python setup.py develop
  </code></pre>
  
  <p>This seems to run just fine, dependencies installed and all:</p>
  
  <pre><code>running develop
  running egg_info
  writing requirements to MyApplication.egg-info\requires.txt
  writing MyApplication.egg-info\PKG-INFO
  writing top-level names to MyApplication.egg-info\top_level.txt
  writing dependency_links to MyApplication.egg-info\dependency_links.txt
  reading manifest file 'MyApplication.egg-info\SOURCES.txt'
  reading manifest template 'MANIFEST.in'
  warning: no files found matching 'rpm\*.json'
  warning: no previously-included files matching 'dev_*' found under directory 'MyApplication'
  writing manifest file 'MyApplication.egg-info\SOURCES.txt'
  running build_ext
  Creating c:\users\eclaird\work\env\lib\site-packages\MyApplication.egg-link (link to .)
  Adding MyApplication 1.2.30 to easy-install.pth file
  Installing MyApplication-do-stuff.py script to C:\Users\eclaird\work\env\Scripts

  [... snip ...]
  
  Finished processing dependencies for MyApplication==1.2.30
  </code></pre>
  
  <p>But I get this error when I try to run the application script:</p>
  
  <pre><code>(env) C:\Users\eclaird\work\MyApplication&gt;MyApplication-do-stuff.py -c dev-config.json
  Traceback (most recent call last):
    File "C:\Users\eclaird\work\env\Scripts\MyApplication-do-stuff.py", line 4, in &lt;module&gt;
      from pkg_resources import require; require('MyApplication==1.2.30')
    File "build\bdist.win-amd64\egg\pkg_resources.py", line 2793, in &lt;module&gt;

  </code></pre>
  
  <p>These same steps have worked fine on my Mac. What's the problem here?</p>
