Need help getting Firewalk to compile.

Can anyone help me install Mark Shiffman's Firewalk? There doesn't seem to be any ports available through Fink or MacPorts and nothing seems to come googling it. I've copied over the config.guess and config.sub files and tried to compile it. Installed libnet11 using MacPorts. One of my co-workers added it to the path and he got the configure to work but the Make step throws all kinds of errors. TIA. --john.endahl@sbcglobal.net
