I was just talking to one of the researchers here who's built it, and
pointed out the completely obvious (once he pointed it out): the "<blank>
not a dynamic executable" tells you that that piece, at least, is
statically linked, *not* dynamic. He recommends getting a core dump, so
you can do a traceback.
