Hey, cool update as this fixes the previous initial Heorku build issues.

Have you tried to add an admin user with fabmanager? There are a few errors - click seems to be missing, I tried installing it but now it gives me an error about init.py and app.py, neither of which I can find.

Yes, could you send more details about the error?
