pinax / django installation on virtual env, run on mod_wsgi

Question

Hi, I tried to install Pinax development version by using pip and virtual environment. It was running on 127.0.0.1:8000 very well. However, when I deployed it on Apache 2 using mod_wsgi, it began to raise exception with the following error :

SystemError: new style getargs format but argument is not a tuple

Any suggestions? I appreciate

Note: I used postgresql as my database.

And here are the wsgi conf file for appache followed by the error log:
