I tried building your project with my environments.
This must be something associated with my specific environment:

I'm using msvc 9.0, which I doubt is significant here.
BOOST_ROOT is C:\c++\boost_1_39_boostpro.
The contents of the BOOST_ROOT is an installation of the BoostPro
distribution of boost, installed using their installer.

Here's the error from the build attempt:

I'm assuming that the first two "cannot find" errors are due to my
lack of a user-config or system-config file in the usual places.

Thinking it might be something specific with the boostpro
distribution, I also have a source install of boost_1_39 which I built
myself, using a downloaded binary of bjam. (boost-jam-3.1.17-1-ntx86).

That BOOST_ROOT=c:\c++\boost_1_39_0, and it was built by running:
bjam toolset=msvc --with-system --with-serialization --with-thread
--with-filesystem --with-date_time --build-type=complete variant=debug
stage

When I try to build using that distribution, I get:
-----

Same problem, it seems.

Appreciate the help / any ideas.
