Relative prefix for django urlpatterns?

Question

I tried doing something like

urlpatterns = patterns('.persons.views',

)

in my urls.py file with the directories looking like

main folder
\profile
    \person
        urls.py <- this is the file
    urls.py

but I got the error "relative imports require the 'package' argument"

I could do 'profiles.persons.view' as the prefix, but I want to try to do a relative prefix like a relative import. How do I fix this such that the relative prefix works? I'm using django 1.4 and python 2.7.
