I've tracked this down to a borland compiler issue.  I've made the fix on my 
local system but don't know where to check it (RC or Dev) yet.  I don't know 
if this fix will make it into the 1.33 release but here it is:

at export.hpp line 204 replace:

typedef BOOST_DEDUCED_TYPENAME mpl::eval_if<
is_abstract<T>,
mpl::identity<abstract>,
mpl::identity<not_abstract>
>::type type;
return std::pair<const void *, const void *>(
type::invoke(),
& guid_initializer<T>::instance
);

with

typedef BOOST_DEDUCED_TYPENAME mpl::eval_if<
is_abstract<T>,
mpl::identity<abstract>,
mpl::identity<not_abstract>
>::type typex;
return std::pair<const void *, const void *>(
typex::invoke(),
& guid_initializer<T>::instance
);

Note the new "x" in "typex"
