Sorry for slow reply, was busy weekend.

I can't reproduce this issue with your code by doing the following:

1. Create fresh Python virtualenv and activate it.

2. Install packages from requirements.txt.

3. Install mod_wsgi using pip to get mod_wsgi-express.

4. Fix start.wsgi to use:

    #sys.path.insert(0, '/var/www/sites/api/')
    sys.path.insert(0, os.path.dirname(__file__))

Although not strictly needed as am running with mod_wsgi-express out of that 
directory anyway.

5. Run mod_wsgi-express as:

    mod_wsgi-express start-server start.wsgi

6. Hit endpoint.

    curl http://localhost:8000/test <http://localhost:8000/test>

Perhaps you can try the same with fresh virtualenv and then try it with 
existing virtualenv. Maybe it will show out something as being strange in your 
virtualenv, or that it comes back to how things are setup with your main Apache 
installation.
