No, the build is right, i.e. intentional.  Please read the URL as
suggested by Olaf, it really does explain everything.  Also please
follow the advice in

http://www.boost.org/doc/libs/1_36_0/libs/python/doc/building.html#no-install-quickstart

for people like you who want to use build systems other than bjam.  It
will potentially save you a great deal of pain.
