Fix problem on 32bit machines. Somehow on32bit machines the linking of libgeant321 is differnt from the linking on 64bit machines. The problem ist that the library dependency to libPythia6 is not explicitly in the link command, so that at runtime there are some symbols which can't be resolved. Overcome this problem by loading the Pythia6 library before loading the geant3 library. This way the library is there and the symbol is known.
