All, I have a problem in starting my Python(Django) App using Apache and Mod_Wsgi
I am using Django 1.2.3 and Python 2.6.6 running on Apache 2.2.17 with Mod_Wsgi 3.3 When I try to access the app from Web Browser, I am getting these errors.

I assume that those missing runtime definitions are supposed to be in the Python executable. Doing an nm on the first missing symbol reveals that it does exist. root [zibal]% nm /usr/local/bin/python | grep -i PyArg_UnpackTuple .PyArg_UnpackTuple T 268683204 524 PyArg_UnpackTuple D 537073500 PyArg_UnpackTuple d 537073500 12 PyArg_UnpackTuple:F-1 - 224 Please guide.
