webhelpers was installed, tested a page that had pagination, first error is:
raise NotImplementedError("no URL generator available")
This appeared to rely on Pylons with a fallback to requiring routes. Once routes was easy_installed, the following error was received:
AttributeError: 'thread._local' object has no attribute 'mapper'
From discussions with mcdonc regarding flash messages, using thread._local appears to be incompatible with Pyramid.
