Ahaaaa. Nothing like posting your question to jog a thought that leads you to the answer.

I realized I should dig deeper into the error:

$ python -Werror manage.py runserver

With that stack trace, I get a line showing:

File "/Users/mboszko/.virtualenvs/opticaldev/lib/python2.7/site-packages/django_date_extensions/fields.py", line 99, in

class ApproximateDateField(with_metaclass(models.SubfieldBase, models.CharField)):

So, the use of SubfieldBase is actually inside a package, I had installed, django-date-extensions. This was at 1.1.0 in my virtualenv, and once I did pip install --upgrade django-date-extensions to bring it up to 2.0, the error disappears.

Fixed!
