ImportError: cannot import RequestSite name when "registration" is enabled in installed applications

Question

I try to install and run Django-registration-redux, and whenever I try to include "registration" in installed applications, I get an error message:

Traceback (most recent call last):

    from django.contrib.sites.models import RequestSite
ImportError: cannot import name RequestSite

I recently installed Django in myenv virtualenv. manage.py runningerver works fine and loads the admin page without the "sign up" application. FYR: I am using python27, and here is my freeze for myenv:

> pip freeze
Django==1.9
django-registration-redux==1.2
wheel==0.24.0

and settings.py include the following applications:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'registration',
]

Do you have any idea what the problem is?
