Horizon plugins for Manila and Magnum

I need to install Openstack Horizon plugins for Magnum and Manila. Magnum-ui is not available on Launchpad; Manila-ui is available but package is broken and patch fix is available in source (version 2.1.0-2). Both project websites give instructions for setting up Openstack virtual development environments, cloning GIT, and building components from source, which I have done. However, I am unclear on how to deploy these projects into my existing Openstack Mitaka environment once I have built them. Can someone please clarify what my options are for getting these plugins to work?

So, to clarify my question: Is there a general procedure for moving locally built horizon plugins into my deployed Horizon instance?

I following instructions for building magnum-ui component for Openstack Horizon here: https://github.com/openstack/magnum-ui

My question is, do I then perform: 1. ~/magnum-ui$ sudo cp -R magnum-ui /usr/share/openstack-dashboard/openstack_dashboard/dashboards

    ~/magnum-ui$ sudo ln -s /usr/share/openstack-dashboard/openstack_dashboard/dashboards/magnum-ui/magnum_ui/static/dashboard /usr/share/openstack-dashboard/static/magnum-ui

    ~/magnum-ui/magnum-ui/magnum_ui/enabled$ sudo cp *.py /usr/share/openstack-dashboard/openstack_dashboard/enabled/

    sudo service apache2 restart sudo service memcached restart

NOTE: this procedure does not work, apache gives an error, so there must be missing steps. I cannot FIND ANY GUIDANCE for how to integrate these Openstack Horizon dashboards into my running deployment.

Thank you!
