Did you follow this part of the instructions at
http://boost.org/libs/python/doc/tutorial/doc/html/python/hello.html:

  After a successful build, you make it possible for the system to
  find boost_python.dll or libboost_python.so (usually done with
  LD_LIBRARY_PATH, DYLD_LIBRARY_PATH, or some other variable on *nix
  and with PATH on Windows) and for Python to find the hello module
  (Done with PYTHONPATH on all systems.)

??

If you don't know what that means, I suggest you follow
http://boost.org/libs/python/doc/building.html instead.  In
http://boost.org/libs/python/doc/building.html#basic-procedure, one
command will build *and* test a Python extension module for you.  If
you add -d+2 to your bjam command line, you can see everything that
the system does to make that happen.
