Advanced Tutorial (how to write reusable app), last step does not work


I am a new newbie to Django.  Great tutorial BTW.  I followed it to the T and 99.9% worked.
Except the last step in the Advanced tutorial, the step 3 in 'Using your own package'.
I could see http://127.0.0.1:8000/admin/ and create polls without any problem.
But http://127.0.0.1:8000/polls/ would give me the following error.

I see there are two problems.
1. /Users/nnn/django_exercises/mysite/templates/polls/index.html is the wrong location, it should be $$/django_polls/polls/templates/polls/index.html.
2. What is 
polls/poll_list.html?  Nowhere in the tutorial ever created this file, no?

Thanks for any advice.
