rosdep-source not included in python-rosdep ubuntu package

I have a stock install of the python-rosdep debian package on Ubuntu 12.04 Precise (version 0.10.12-1).  The package does not include the rosdep-source script, so source installs always fail, as shown below.  Installs work correctly if I manually download rosdep-source (e.g. from https://raw.github.com/ros/rosdep/master/scripts/rosdep-source) and place it on my path.

    $ rosdep install mypackage
    Executing script below with cwd=/tmp
    {{{
    #!/bin/bash
    dpkg-query --show --showformat='${Status}' myrosdep | grep --quiet ' installed$'
    exit "$?"
    }}}

    {{{
    #!/bin/bash

    exit "$?"
    }}}

    executing command [rosdep-source install http://my.host/path.to.rdmanifest]
