I tried to install fabrik to a slave using jms tools and it didn't install any of the "plugins" which are not joomla plugins but component plugins. They are needed for fabrik to function on the front end at all...since I had already built my app I installed over it using the regular joomla install function on the slave. This fixed errors, but still some quirks and I am not sure who's end it is on, will let you know if I find anything of significance.

When you use the JMS tools, you have can decide yourself what you install.
If plugins are required, you have to select them in the JMS Tools / Plugins panel as you do it with a component or module.

So in JMS Tools, select the slave site and after browse in each tabs (components, modules, plugins) to decide what you want install.
Normally the plugin required by Fabrik must be there.
