The correct path should be .../src/, I believe.
Actually, if you're working with an installed
Boost.Build you're better off just deleting
boost-build.jam. I believe that python/example/boost-build.jam
should be removed from the repository.
- If you are running inside the full boost
distribution, it will work, but is useless,
because the top level $BOOST_ROOT/boost-build.jam
works just as well. (Actually it won't work,
because it uses an out-of-date path, but that's
- If you are using this part of Boost.Python standalone,
(as you appear to be doing), the path will be wrong,
and it will fail, with the error that you're seeing.

This is a later problem. The jamfile for your
example is trying to reference the BOOST_ROOT
