Not able to run django-testapp

[conteit]

I tried to configure (both on Windows 8.1 and MacOS X Yosemite) in order to run django-testapp, because I'm interested in developing a django webapp on gae.

I'm using Python 2.7.6 on Mac and 2.7.9 on Windows.

First attempt: Installed latest GAE SDK (1.9.17), cloned django-testapp, ran build.sh script. Then I tried to execute "python manage.py runserver", but I've got an error about dev_appserver.

I googled this issue and found that somebody was able to start the server by using "devappserver2" branch on django-appengine and GAE SDK 1.9.14, so I decided to give it a try.

Second attempt: GAE SDK 1.9.14, devappserver2 branch. With this setup runserver worked. Since I'm intereseted in django admin site, I tried the createsuperuser command but I've got the following traceback:
