It seems like this doesn't work anymore with Django 1.0 (primarily due to absence of sql_model_create).

I got pretty much the same results with this:

## With directory layout:

settings.py
orm/
    __init__.py
    models.py

## With content:

# settings.py
DATABASE_ENGINE="sqlite3"
DATABASE_NAME="database_name.db"

INSTALLED_APPS = ('orm')

# models.py
from django.db import models

class SomeModel(models.Model):

Then running either of the following commands:

django-admin.py sqlall --settings=settings --pythonpath=. orm

django-admin.py syncdb --settings=settings --pythonpath=.
