  <p>I have started to translate my project. I have sucessfully translated everything that was in <code>my_django_project</code> which is the actual django project. I have 2 apps installed with <code>python setup.py develop</code>, that are located outside the django project scope. I don't seem to be able to run the <code>makemessages</code> command. Running it with the <code>manage.py</code> helper doesn't find the apps in the <code>apps</code> folder. i.e nothing has been added to <code>locale/fr/LC_MESSAGES/django.po</code>. It worked fine for <code>appA</code> and <code>appB</code> located in <code>my_django_project</code>.</p>
  
  <p>How do I run make messages for these apps located outside the django project ?</p>
