You need to link with all plugins from which symbols you use. There is a
function called linkPlugins, so you will have to say something like:

env.SharedLibrary(....,LIBS=env['LIBS']+['nacg_nac']+linkPlugins(['InteractionGeometryFunctor','OtherClassYouUse']));

have a look in py/SConscript for inspiration; you need to put _file_
names where those classes are defined rather than _class_ names
themselves. linkPlugins will make sure that depending on build type
(per-class vs. monolithic), it will add the right LIBS.

Classes from core/ and lib/ are loaded automatically, no need to add
those by hand.

You're just 1 step from your plugin working (and there you start real
debugging ;-) )
