Did you actually use 

        --address-model=64

command line option? If so, this is wrong, according to:

        http://www.boost.org/boost-build2/doc/html/bbv2/advanced/invocation.html

you should use

        address-model=64

Define BOOST_LIB_DIAGNOSTIC to 1 when building your application,
then examine the output, and then follow the procedure at:
