I just started a new project using the latest release candidate of Django 1.5. One thing that I needed was the local flavor add-on so I could get a list of US states. This functionality used to be rolled into the main codebase, but it was rightfully removed in Django 1.5. To install the US local flavor package, just use PIP.
pip install https://github.com/django/django-localflavor-us/zipball/master
Now you should be able to import anything you need from the package in the usual manner, except from the new package instead of the old one.
from django_localflavor_us.us_states import STATE_CHOICES
For more information, check out the How To Migrate section of the local flavor docs on the Django documentation site.
