Answer 1

Su url para admin debe ser:
url(r'^admin/', include(admin.site.urls))
no (r'^admin/(.*)', admin.site.root)
- es de Django 1.0. Para Django 1.3 no funcionaría.

Answer 2

Otro posible problema aquí, que me encontré, es que el administrador no se ha configurado correctamente en el archivo settings.py. Cualquiera que tenga este problema querría comprobar que sus aplicaciones instaladas incluyen django.contrib.admin. Referencia https://docs.djangoproject.com/en/1.3/faq/admin/ para más detalles.
