Problem 479

I wanted to try the Bertini cascade model now that the physics lists
(LHEP_BERT) for Geant 4.5.0 have been released.

Compiling my app I get a linker error:
/home/ersmark/sim/g4/lib/Linux-g++/libPackaging.so: undefined reference to
`G4CascadeInterface::G4CascadeInterface(void)'

This happened when using global shared libs. Using granular shared libs my
app links fine.

For global libs  I dont get any output from "nm libG4processes.so | grep
G4CascadeInterface". For granular libs "nm libG4hadronic_bert_cascade.so |
grep G4CascadeInterface" gives:
