Hello,
I cannot help you with that error (I am a Linux user), but I would
suggest you to try the more recent version of boost-numeric_bindings
that you can find in the Boost sandbox:
https://svn.boost.org/svn/boost/sandbox/numeric_bindings/
You can download it through Subversion:
svn co http://svn.boost.org/svn/boost/sandbox/numeric_bindings
boost-numeric_bindings
Hope this helps.
Best,
-- Marco
