Its look like that lookup_basic_helper/insert_basic_helper has not been 
added to polymorphic_iarchive/polymorphic_oarchive and
polymorphic_iarchive_impl/polymorphic_oarchive_impl classes by mistake. 
Also, interface_iarchive and interface_oarchive members lookup_helper and

insert_helper should be transformed from

    void lookup_helper(
        const boost::serialization::extended_type_info * const eti,
        shared_ptr<void> & sph
    ){
        this->This()->basic_iarchive::lookup_basic_helper(eti, sph);
    }

 to

    void lookup_helper(
        const boost::serialization::extended_type_info * const eti,
        shared_ptr<void> & sph
    ){
        this->This()->lookup_basic_helper(eti, sph);
    }

This works for me.
