Yes, I remember this issue. I've reported this earlier. If I use
point_xy instead of point as a base point type there is an compilation
error in geometry\algorithms\convert.hpp:

'boost::mpl::assertion_failed' : cannot convert parameter 1 from
'boost::mpl::failed ************(__thiscall
***********)(boost::mpl::assert_::types<T1,T2>)' to
D:\lib\boost_geometry\boost\geometry\algorithms\convert.hpp 226

Is this what you have in mind?

Inside rtree I use geometry::point as my basic point because user may
use whatever he/she wants. But conversion from
geometry::box< geometry::point<...> > to
geometry::box< geometry::point_xy<...> >
is not implemented in geometry::convert().

Please just use geometry::point for now.
