    When I've done things like this myself, I've usually forgotten to
    install the sources.list entry, or forgotten to run `apt-get
    update`; and subsequently been very confused for a short period of
    time. Next time, it might be worth double-checking with `dpkg -l` on
    both boxes as a sanity check.<br>

                That is a very odd looking error. The rabbit_control
