Cannot pass step: videocache-1.9.1 # python setup.py install

I have installed squid and its running fine
now i am trying to install videocache

First i did # python setup.py install [in videocache-1.9.1 folder]
But at that time python-iniparse was not installed

I then installed iniparse, but now when i try to do # python setup.py install i get the following errors:

vpro:/home/ztel/videocache-1.9.1# python setup.py install
Traceback (most recent call last):
File "setup.py", line 397, in
setup(root)
File "setup.py", line 288, in setup
if not dir_perms_and_ownership(new_dir, squid_user, squid_group):
File "setup.py", line 76, in dir_perms_and_ownership
user = pwd.getpwnam(user)[2]
KeyError: 'getpwnam(): name not found: squid'
vpro:/home/ztel/videocache-1.9.1#

and here is the videocache setup log
