Broken library in Django 1.6 - urls reverse / NoReverseMatch even when templates corrected

Question

Using django-pendulum and trying to get it to work w/the latest Django 1.6. Using a sample blank project, it seems to break trying to reverse urls. I even escaped the {url..} syntax in the templates but no luck. Any ideas on how this can be fixed to work w/1.6? It worked in 1.5!

EDIT - here is the error:

NoReverseMatch at /pendulum/
