Those instructions don't look they tell ovsdb-server to listen to a TCP socket.  It looks like it's setting up a unix domain socket to "/usr/local/var/run/openvswitch/db.sock".  Depending on how you built ovsdb-client, the default path it uses may just work.  If it doesn't, you'll likely need to tell it by adding "unix:/usr/local/var/run/openvswitch/db.sock" to the command.
