The above looks good to me.

Note that in subsequent versions of the library and documentation the
BOOST_CLASS_EXPORT... macros have been redesigned somewhat to separate
declaration from instantiation.  The older macros you're using can work but
they are confusing to get right.  Look at the latest documentation to see
the difference.  You can then either then tweak your code to work with the
older macros or use a later version of boost.  In any case, reading the more
recent documentation should help clarify what is going on.
