Import error

[RealBigB]

• pip install django-filer==0.9.4
• upgrade django from 1.4.1 to 1.4.2 because django-filer needs django.utils.six :(
• pip install cmsplugin-filer
• ./manage.py syncdb & ./manage.py migrate
• pip install django-cms-events
• add "cmsplugin_events" to settings.INSTALLED_APPS
• ./manage.py syndcb

Result:

And there's indeed no module or package model_utils in sight. After a bit of googling it appears that it's another missing dependency on https://bitbucket.org/carljm/django-model-utils
