url lookup not working?

I'm reading Bennets Practical Django Projects and I'm stuck on chapter
6, on templates.

The error I get is:
"Caught an exception while rendering: Could not import
django.views.generic_list_detail. Error was: No module named
generic_list_detail"
with this line highlighted:
20 <li><a href="{% url coltrane_entry_archive_index %}">Entries</
a></li>

I've followed the book pretty tightly, and get the following
traceback:

My URL config sends requests to /blog/ to this file (entries.py):

from django.conf.urls.defaults import *
from coltrane.models import Entry

entry_info_dict = {
'queryset': Entry.objects.all(),
'date_field': 'pub_date',
}

urlpatterns = patterns('django.views.generic.date_based',
(r'^$', 'archive_index', entry_info_dict,
'coltrane_entry_archive_index'),
(r'^(?P<year>\d{4})/$', 'archive_year', entry_info_dict,
'coltrane_entry_archive_year'),
# the genereic view expects month format as %b, I use %m. Need to
inform of that
(r'^(?P<year>\d{4})/(?P<month>\d{2})/$', 'archive_month',
dict(entry_info_dict, month_format='%m'),
'coltrane_entry_archive_month'),
(r'^(?P<year>\d{4})/(?P<month>\d{2})/(?P<day>\d{2})/$',
'archive_day', dict(entry_info_dict, month_format='%m'),
'coltrane_entry_archive_day'),
(r'^(?P<year>\d{4})/(?P<month>\d{2})/(?P<day>\d{2})/(?P<slug>[-\w]+)/
$', 'object_detail', dict(entry_info_dict, month_format='%m'),
'coltrane_entry_object_detail'),
)

I'm not really sure where to check what to solve this, any
suggestions?
