It may be a good idea to investigate if libnet does your job. The ports version (net/libnet-devel) is based on libnet-1.1.2.1. Mike Schiffman, who writes libnet may have a newer version on his site: http://www.packetfactory.net/projects/libnet/ If you do decide to use libnet, I also have a few local patches that may be interesting; mostly updates lto ibnet's build tree that use the latest automake and autoconf or changes to libtoolize libnet; these are "local hacks" though.
