Django broken

I was working a tutorial and one of their points was that you should be able to create a project and it will just run. Unfortunately, that doesn't work with IDEA + Python plugin.

I get the output below. If django-admin.py is deprecated, why is IDEA still calling it?

And other issues.

No manage.py file specified in Settings->Django Support
