This is probably a pretty basic question.

I'm setting up a project in which I'd like to import certain pathnames from the
environment. I've got just two jam files in the root directory,
"boost-build.jam" and "Jamroot", with the following contents.


    # This works; the environment variable DN_BOOST contains
    # the root of my boost_1_33_1 installation
    boost-build $(DN_BOOST)/tools/build/v2 ;


    echo ****** ;
    echo $(DN_BOOST) ;
    echo ****** ;

When I run bjam --v2, I get:


   ...found 1 target...

Why does $(DN_BOOST) expand to an empty string in Jamroot but not in
