You will need get boost/math/special_functions from the trunk - Steven
just
checked in some revisions that replaced our ad hoc implementations of
some
of these math functions with those defined in Boost.Math.

This is probably because you need to convert the base unit into a unit
by qualifying with unit_type :
typedef
boost
::units
::quantity
<boost::units::survey::yard_per_sec_base_unit::unit_type,double>
YardsPerSec;
We should see if there is a way to at least warn in these cases...
