So, something is strange. <snip> 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. mark
