At least part of the problem is that it isn't looking for
Jamfile.v2. That will only happen if you use -sJAMFILE=[Jj]amfile.v2
on the command-line OR pass --v2 and use a version of the
$BOOST_ROOT/boost-build.jam in your project's root directory.

The rooting problem I think can be solved this way. Try changing:

project.use $(id) : [ path.root $(where) [ $(attributes).get location ] ] ;

to 

project.use $(id) : [ path.root [ path.make $(where) ] [ $(attributes).get location ] ] ;
in $BOOST_ROOT/tools/build/new/project.jam

Please let us know if that works.
