Uh, oh. I did not even notice you're using those low-level tricks. I'd suggest using:

        stage $(target)
                : <sources>
                : <location>$(BOOST_LOCAL_STAGE_DIR)/$(libtype)/$(libname)/$(variant)
                  ...........

and removing NOTFILE and DEPENDS completely.
