unable to run Heroku tutorial app locally - django

Question

I'm following the getting started with Python tutorial at Heroku, and I'm stuck at the "Run the app locally" step. I'm on a Windows 7 machine, and I've managed all previous steps successfully. The following code was run in the Git Bash provided by the toolbelt inside a virtualenv as described. The error appears below.
The ProcFile says (as per the instructions)
web: python manage.py runserver 0.0.0.0:$PORT
and the command foreman start web fails with the error depicted below.
If I just enter python manage.py runserver 0.0.0.0:5000 into the prompt, the server starts right up and I can visit the app. Maybe this is sufficient to develop locally, but maybe not, so if anyone can shed some light on what's going on, I'd be grateful. Thank you.
PS: I should also emphasize that as per this step gunicorn was worked out of the requirements, so unlike many questions similar to this, gunicorn is not supposed to be part of the picture.
