[boost] [python] Bug during build process?

Hi, I execute the following command to build the entire boost 1.37 library with python debugging ON: *bjam --toolset=msvc --layout=system link=shared threading=multi variant=debug python-debugging=on stage* I then use dependency walker <http://www.dependencywalker.com/> to load the file *boost_python-mt-gyd.dll* and I see that both python25.dll and python25_d.dll are being loaded side by side. This obviously shouldn't be happening and only python25_d.dll should be loaded. Is there a bug in the build script for boost python, or am I doing something wrong?
