The problem is that both libfluxus and libode have a class with the same 
name "dMatrix", and somehow things get confused and mixes up different 
operations from the different implementations at runtime, = BOOM...

The quick solution is to put the fluxus dMaxtrix into a different C++ 
namespace: in dada.h and dada.cpp something like

namespace fluxus {
... all definiitions ...
};

and add

using namespace fluxus;

to any file that complains when you rebuild.
