bitbake (http://cgit.openembedded.org/cgit.cgi/bitbake/) is a
make-alike build tool with the special focus of distributions and
packages for embedded Linux cross compilation,it provide -g option

-g, --graphviz        emit the dependency trees of the specified packages in
                        the dot syntax

it's great!
