When running Django, it complains that psycopg is not installed.
The easy fix is to install psycopg2-2.0.2-py2.4-macosx10.4.zip that can be found here: http://pythonmac.org/packages/py24-fat/
Then you need to change this line in settings.py:
From:
DATABASE_ENGINE = 'postgresql' # 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
To:
DATABASE_ENGINE = 'postgresql_psycopg2' # 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
