Apparently it works if you add an extra level of indirection:

template<class>
struct make_member_hook {
    typedef 
boost::intrusive::member_hook<EqualRefSystem,EqualRefSysHook,&EqualRefSystem::ERSMemberHook> 
type;
};

//! Objects that reference this EqualRefSystem
boost::intrusive::list< EqualRefSystem,
    typename make_member_hook<EqualRefSystem>::type,
    boost::intrusive::constant_time_size<false> > ReferencedBy;

In Christ,
