I must have misunderstood the BBv2 installation instructions then when I 
read

   When bjam is invoked, it always needs to be able to find the
   Boost.Build root directory, where the interpreted source code of
   Boost.Build is located. There are two ways to tell bjam about the
   root directory:

     * Set the environment variable BOOST_BUILD_PATH to the absolute
       path of the Boost.Build root directory.

(The second way is using boost-build.jam as you wrote)
