Running example app does not work

[gonvaled]

I have:

• created a virtualenv (3.4)
• activated the virtualenv
• installed all dev requirements (and also all requirements, which are actually empty)
• installed the package with -e

Doing runserver crashes with:

django.core.exceptions.ImproperlyConfigured: Requested setting DEFAULT_INDEX_TABLESPACE, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

I am on commit 59f5da9 (develop branch)
