This script will patch whichever paramiko package is currently installed. (To patch a virtualenv, first activate the virtualenv).
This script should work on Linux and OS X. (untested)
This script will also work on Windows if you have added C:\Program Files\Git\usr\bin to your system Path environment variable. (tested)
