That should work without any special effort.  I wonder whether your
ovs-ofctl is looking for the software in the same directory where
ovs-vswitchd created it.  If, for example, you had some version of
ovs-ofctl in your $PATH that was compiled with a rundir different from
the running ovs-vswitchd, then that would explain the problem.
