    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.
