This can be solved in changing the order of the libraries in gconfig/g4libs.
The real problem is that geant4 don't run with root 5.14.00 but
needs root 5.16.00 which envorces big changes in the framework.
So the step to geant4 9.0 is not easy to make.

I will try to ask the GEANT4 people for advice.

Ciao
