How to install rabbitmq management plugin (rabbitmq-plugins)

Brief: Is there a way to install rabbitmq-plugins via a ubuntu package? Details: I have rabbitmq running ok in my ubuntu system, and now I'm trying to monitor what's going on via the management plugin. I'm following rabbitmq.com/management.html instructions, but can't execute rabbitmq-plugins enable rabbitmq_management because my system does not have rabbitmq-plugins installed. It's Ubuntu 1110, and came with rabbitmq installed as a package (aptitude install rabbitmq-server librabbitmq-dev). The config and the server are running fine (the installed version is 2.5.0). Thought that the plugin would get installed by installing "sudo aptitude install rabbitmq-plugins-common", but doing that does not install rabbitmq-plugins. Is there a package that will install the plugin? I'd like to avoid if possible having to purge the rabbitmq server that is running ok, and then reinstall it via a download + build from source, all just to get the plugin. Thanks.
