If you want help you really should try to answer some of the questions
I asked in my previous email. It happens that I have some experience
with the packages you are trying to use, but you seem to be using them
in a configuration I am not familiar with (i.e. you generated a
standalone demo that you want to distribute?).

It is important I know where you got the packages, how you built them,
and even better, what precisely you are trying to do with them; it
sounds almost like this is a question more suited to ROOT/Geant4
developers than this mailing list.
