I found a post on this group about this issue: http://lists.macosforge.org/pipermail/macports-users/2007-March/001927.html but it was not very helpful. I am trying to set up a django dev environment on my macbook pro tiger. I am a newbie switcher, and I have been trying to get this working for over a week now. I wrote up my setup for the system (so far), in the following blogpost: http://shinmaikeru.blogspot.com/2007/12/howto-django-dev-environment-on-maco... The errors I get are as follows: ------ netadminmac:~/Webdev/django/sites/mysite mcooper$ python manage.py runserver Validating models... Unhandled exception in thread started by <function inner_run at 0x11c2970> Traceback (most recent call last): File "/opt/local/lib/python2.5/site-packages/django/core/management/commands/runserver.py", line 47, in inner_run self.validate(display_num_errors=True) File "/opt/local/lib/python2.5/site-packages/django/core/management/base.py", line 112, in validate num_errors = get_validation_errors(s, app) File "/opt/local/lib/python2.5/site-packages/django/core/management/validation.py", line 22, in get_validation_errors from django.db import models, connection File "/opt/local/lib/python2.5/site-packages/django/db/models/__init__.py", line 3, in <module> from django.core import validators File "/opt/local/lib/python2.5/site-packages/django/core/validators.py", line 11, in <module> import urllib2 File "/opt/local/lib/python2.5/urllib2.py", line 88, in <module> import hashlib File "/opt/local/lib/python2.5/hashlib.py", line 133, in <module> md5 = __get_builtin_constructor('md5') File "/opt/local/lib/python2.5/hashlib.py", line 60, in __get_builtin_constructor import _md5 ImportError: No module named _md5 ------ Any help would be appreciated.
