I've repeated all the steps and still getting the error.
It happens when jsonrpc tries to use rabbit_mochiweb_registry. Erlang
complains that the proc is not registered.

I know. I'm trying to create a plugin that uses the mochiweb plugin but got
errors so I've tried using the jsonrpc
plugin as a reference but got the same errors.
I'll try to remove the umbrella folder and repeat all the steps.
There is also a bug in the rabbit_metronome hello-word example
rabbit_metronome_worker/init calls amqp_connection:start_direct(<<"guest">>,
but there is no amqp_connection:start_direct/2. I think it should be
amqp_connetion:start_direct() because guest is the default.
