Suppose that you specify --prefix=/usr/local. Then, libraries go to /usr/local/lib and headers
go to /usr/local/include -- where a directory boost-1_42/boost is created. Then, if you
specify --libdir=/usr/local/lib --includedir=/usr/local/include the effect is the same.
In other words, --includedir is not specifying where top-level boost headers are installed,
it specifies the root directory where includes live and boost-1_42/boost is created under

Because "bjam" and "bjam install" are meant to do different things. It's useful to be able to
build Boost and not install it anywhere -- in particular if you regularly update from SVN
and rebuild, there's no reason to keep a second copy of all headers in a location different
from your SVN checkout.
