        I'm in the process of testing the attached patch, basically
        just had to remove a portion of the match for the `Control
        Outlet' option.

        here is the clusternode elem I'm using, with the port
        specified, and seems to work so far.  as far as I know, this
        must be specified in the cluster.conf manually.

<clusternode name="node1" votes="1">
    <fence>
        <method name="pdu">
            <device name="pdu" port="1"/>
        </method>
    </fence>
</clusternode>

        hope this helps.
