Not able to login into pyf(TypeError: url() got an unexpected keyword argument 'came_from' when clicking on login button)

[Anoop]

Hi,

   I am new to pyf, I installed pyf using virtualenv in my ubuntu 12.04 box with python 2.7

easy_install -UZ pyf.services
easy_install -UZ pyf[components]

and I configuraed pyf as mentioned here http://pyfproject.org/en/getting-started/configuring using postgresql9.1

and paster serve pyfservices.ini created the table structure and populated necessory data like tg_user.

paster serve pyfservices.ini also running without errors

 paster serve pyfservices.ini
