Solution 1:

Do you have this

from django.conf.urls.defaults import patterns, include, url

in your urls.py?

Solution 2:

It seams that you forgot the from django.conf.urls.defaults import * or from django.conf.urls.defaults import include in your urls.py.

Solution 3:

You probably haven't imported it:

from django.conf.urls.defaults import include

In general, when it says that something is not defined, it means that the compiler can't resolve something. This is usually caused by missing import statements or spelling errors.
