Ok. I figured out what I was doing wrong with regard to the WebHelpers issue.
Essentially when installing my pylons application egg. It was dependent upon 0.6.4. It did not find the application and then attempts to retrieve a best match from webhelpers which is obviously conflicting with 0.9.7. I did have the egg of webhelpers of 0.6.4 which is now compatible with 0.9.7. Snails pace at the moment.
