That's because you have rabbitmq-mochiweb installed (which allows 
multiple plugins to serve web contexts on the same socket) but do not 
have any plugins installed that actually provide contexts.

And there's your problem. You have installed all of 
rabbitmq-management's dependencies, but not the plugin itself.

(Those warnings are harmless BTW.)
