No module named 'social_auth' on social/utils.py

When i trying to user Facebook backend the following error appears

Exception Value: No module named 'social_auth'
Exception Location: /home/vyscond/tartarus/partyup/env-partyup/lib/python3.4/site-packages/social/utils.py in import_module, line 16

so i've debbuged with a print function

def import_module(name):
    print(name)
    __import__(name)
    return sys.modules[name]

the return is

social.backends.google
social.backends.twitter
social_auth.backends.facebook

so why the backend for facebook is different?

nevermind! i was using the wrong reference at settings.py (social_auth.backends.facebook.FacebookBackend)

Yes, that's django-social-auth backend, the paths and names changed in python-social-auth.
