If you guys want an ASCII graph plotter, you could rip off the code here: https://github.com/scalability-llnl/spack/blob/master/lib/spack/spack/graph. py#L31
It prints little ascii graphs of dependencies, like git log --graph. Example: o mpileaks |\ | |\ | o | callpath |/| | | |\| | |\ \ | | |\ \ | | | | o adept-utils | |_|_|/| |/| | | | o | | | | mpi / / / / | | o | dyninst | |/| | |/|/| | | | |/ | o | libdwarf |/ / o | libelf / o boost It gets more complicated with things like qt :).
