The usual method should be adequate one of:
% pip install amqpctl
% easy_install amqpctl
If you are interested in the development branch of the code, or to contribute any patches or whatnot, the mercurial repository is http://bitbucket.org/ww/amqpctl . A convenient way of installing for development is to do:
% pip install -e hg+http://bitbucket.org/ww/amqpctl#egg=amqpctl
In any event, having done one of the above, there should now be a command amqpctl that is installed and runnable.
