datastax opscenter installation failed with 'no such option: --post-install' error

Background: I have a 3 node cassandra (1.2.5) cluster and I am trying to install datastax on one of the nodes. I am following instructions from: http://www.datastax.com/docs/opscenter/install/install_deb

I have following already installed:
java -version = 1.6.0_24
python -V = 2.6.6
openssl version = 0.9.8g 19 Oct 2007

Issue: When I run 'sudo apt-get install opscenter-free', the installation starts but errors out with:
update-python-modules: error: no such option: --post-install dpkg: error processing opscenter-free (--configure): subprocess post-installation script returned error exit status 2

Possible root cause: By searching for error I could gather it looks like python issue.

I ran ls to see where python resides, here some results:
ls /usr/local/bin = python python2.6 python2.7
ls /usr/bin/ = python python2.5

As specified before if I run 'python -V' result is 2.6.6.
I don't understand how to make my opscenter installer to look at the appropriate version? or how to understand which python it is referring to?

This is most likely an issue with the following from the opscenter-free package:

# cause any deferred python module compilation (like for telephus) to be done
# now, before the initscript starts
if which update-python-modules >/dev/null 2>&1; then
    update-python-modules --post-install
fi

update-python-modules comes with the python-support package. It looks like the binary is available, but whatever version the install process is finding doesn't recognize the --post-install option.

If which update-python-modules points to an older (<= 2.5) or newer (3.0+) version of the script, you can try removing whatever package is including that, or updating the python-support package.
