[Serusers] SER MediaProxy Phyton Problem

I cannot run the mediaproxy.py program from AG-MediaProxy software. The script cannot import optparse module

Starting SERMediaProxy server: mediaproxyTraceback (most recent call last): File "/etc/ser/mediaproxy/mediaproxy.py", line 21, in ? from optparse import OptionParser ImportError: No module named optparse Traceback (most recent call last): File "/etc/ser/mediaproxy/proxydispatcher.py", line 35, in ? from optparse import OptionParser ImportError: No module named optparse

I have the following rpm packages installed for python:

python-2.2.1-17 libxml2-python-2.4.23-1 rpm404-python-4.0.4-8x.27 python-tools-2.2.1-17 python-optik-1.3-2 rpm-python-4.1-1.06 mod_python-3.0.0-10 python-devel-2.2.1-17
