Oh, this might be mistaken, haven't deleted it yet. My installation had not created an include directory (which is sometimes optional, but possibly not optional for using this package).
Simple fix:
The src/RwCalculators/GReWeightINuke.h
needs
include "Framework/GHEP/GHepParticle.h"
because its part of the method CalcDeltaAZ specified in the .h file
Having it in the .cxx file is not enough, compiler gives unknown type name
