Django avatar util problem

I've got a django project working on a development server(ubuntu) that we have been working on for a good while. I'm trying to install it now locally on my mac book pro.

I'm relatively new to the Django environment (10 years in LAMP). I tried installing all the relevant packages e.g. south, django-registration etc.

I'm having a problem with django-avatar I think though. When I try run the server I get the following error. I'm not sure where to go from here to fix the problem. any tips and general education would be greatly appreciated.

$ python manage.py runserver

It looks like you either have an older (or newer) version of fishpond than django-avatar - fishpond is trying to load up django-avatar's util module, but your version of django-avatar doesn't have a util module. You might want to check and see if there's a certain version of django-avatar that fishpond needs.
