I suspected as much. But I didn't know where to look.

I suspect ../boost/mpi/datatype.hpp: needs some code like:

/// specialization of is_mpi_datatype serialization types
template <>
struct is_mpi_datatype<boost::archive::version_type >
: public boost::mpl::true_
{};

template <>
struct is_mpi_datatype<boost::serialization::item_version_type >
: public boost::mpl::true_
{};

template <>
struct is_mpi_datatype<boost::serialization::collection_size_type >
: public boost::mpl::true_
{};

I would prefer that someone who knows what they're doing
check this and make the changes.
