'django_postgrespool' isn't an available database backend

After installing django_postgrespool and configuring my project accordingly, I received the following error:

Traceback (most recent call last):
  File "C:\Users\Administrator\Documents\my_proj\my_module.py", line 14, in <module>
    from cortex.my_app.models import MyModel

    from django.db import models

    raise ImproperlyConfigured(error_msg)
django.core.exceptions.ImproperlyConfigured: 'django_postgrespool' isn't an available database backend.
Try using django.db.backends.XXX, where XXX is one of:
    'dummy', 'mysql', 'oracle', 'postgresql_psycopg2', 'sqlite3'
Error was: cannot import name Diagnostics

Of course I checked I can import django_postgrespool in the same env.
I found this similar issue, however its resolution was to use django 1.4+ and I'm using 1.4.3

Uninstall psycopg2-2.5.1 and install psycopg2-2.4.6.

I don't know why it solves this problem, when psycopg2-2.5.1 is a requirement of the latest postgrespool. I am using Windows Python 2.7.3 AMD64. I've reported this as a bug to django-postgrespool
