How can I Include an installed module in customer RCP application?

I would think this is something simple that I am missing but I have two different modules that I have installed in NetBeans 8.1, namely the Python module and the Dark Nimbus look and feel module.

I now want to include those in my RCP app to the customer.  I can not seem to figure out how to do this.

The python module features/support don't show up.

When I use the code DarkNimbusLookAndFeel.class.getName() in the validate method of my installer class the IDE can't find the DarkNimbusLookAndFeel class.  I know it is in the module but how can I make it accessible?

Maybe these are two different problems, but they seem similar in that any module I install in NetBeans does not become accessible in my RCP app.  How can I make them available in my RCP app?
