The above is fine for Boost, but CVS HEAD of Boost.Build V2 requires CVS HEAD 
of Boost.Jam. So, you should run boost_root/tools/build/jam_src/build.bat and 
use the binary that is created.

Well, http://www.boost.org/tools/build/index.html mentiones that you have to 
install Boost.Jam before building boost. For building boost, prebuilt 
packages exists. For testing V2, one has to compile Boost.Jam from sources.
