I think it should be .../tools/build/src now.
The point of boost-build.jam is to allow
b2 to find the jam sources for Boost.Build.
It's no longer needed if you're using an
installed version of Boost.Build.

I see several targets in libs/python/example/Jamroot.
python-extension and run-test both declare targets.

There are two spaces between "python" and -gdt.  I'd
guess that's where the name of some python script
is supposed to be.
