Use pip

Install the Python package manager: python-pip Install python-pip.

To install the latest stable version run

sudo pip install dm.xmlsec.binding

or if you need a specific version:

sudo pip install dm.xmlsec.binding==1.0b3

This method using pip is preferred over easy_install or setup.py, because it can keep track of dependencies and updates, much like apt on Ubuntu.
