'instbar' here refers to:

        lib instbar : : <name>bar <search>install ;

which definition say 'ask the linker to search for library bar
in directory install'. However, Boost.Build has no idea how
the linker actually does it -- the linker can find this library
in some "standard" directory, for example. Therefore, it's not
possible to establish dependency on instbar.

Referring to 'util/foo//install' should work better.
