Use boost::ref and/or vector_tie to make it hold references.

#include <boost/fusion/include/vector.hpp>
#include <boost/fusion/include/vector_tie.hpp>
#include <boost/fusion/include/push_back.hpp>
#include <boost/ref.hpp>

class DoNotCopyConstructMe {
public:
   DoNotCopyConstructMe() {}
private:
   DoNotCopyConstructMe(const DoNotCopyConstructMe &ref) {}
};

int main() {
    DoNotCopyConstructMe var1,var2,var3,var4;
    boost::fusion::push_back(boost::fusion::vector_tie(var1, var2, 
var3),boost::ref(var4));
}
