Hard to say. Cleaning up the compiler messages:
=============
cxx: Error: /usr/local/boost_1_18_2/boost/cast.hpp, line 159:

nontype "boost::cast::detail::numeric_min_select<is_signed>::limits
          [with is_signed=(bool)_STL::numeric_limits<T>::is_signed]"
is not a template
numeric_min_select<std::numeric_limits<T>::is_signed>::limits<T>
-------------------------------------------------------^

cxx: Error: /usr/local/boost_1_18_2/boost/cast.hpp, line 159: not a class or
struct name
numeric_min_select<std::numeric_limits<T>::is_signed>::limits<T>
^
cxx: Info: 2 errors detected in the compilation of "py.cpp".
==============

It appears to be complaining that numeric_min_select<T>::limits is not a
template, which it clearly /is/. But since it thinks it is a non-type
parameter, maybe you can fix this problem by changing line 159 of cast.hpp
as follows:

: public typename numeric_min_select<std::numeric...
         ^^^^^^^^

Let me know how it works out.

As I said before, time to start testing with Comeau ;-/
