title: Django - Foreman cannot find installed modeles
body: <p>I am trying to use <a href="https://github.com/ddollar/foreman" rel="noreferrer">Foreman</a> / <a href="https://github.com/nickstenning/honcho" rel="noreferrer">Honcho</a> to manage my Procfile-based Django application. When I start the app view the normal <code>python manage.py runserver</code>, everything works fine. However, when I start the app via <code>honcho start</code> or <code>foreman start web</code>, I am receiving this error:</p>

  <p>This is with attempting to install the <a href="https://github.com/arneb/django-messages" rel="noreferrer">django-message</a> module. I have the same issues with other modules as well. I'm also running into the same issue with <a href="https://github.com/owais/django-webpack-loader" rel="noreferrer">django-webpack-loader</a>. I should also mention that I am receiving the error both within a virtualenv and when it is deactivated. </p>
  
  <p>Here's the command for installing django-messages:</p>
  
  <pre><code>$&gt; pip install django-messages
  Requirement already satisfied (use --upgrade to upgrade): django-messages in ./lib/python2.7/site-packages
  </code></pre>
  
  <p>Installed Apps;</p>
  
  <pre><code>INSTALLED_APPS = (
      'django.contrib.admin',
      'django.contrib.auth',
      'django.contrib.contenttypes',
      'django.contrib.sessions',
      'django.contrib.messages',
      'django.contrib.staticfiles',
      'my_app',
      'django_messages',
  )
  </code></pre>
  
  <p>I'm not sure what other information I can provide to help troubleshoot, but the basic question is how do I get installed apps to work with foreman / honcho?</p>
