    To expand on this just a bit: You can't just compile the tcpdrop
    executable and expect it to work. It requires a newly-built kernel
    (because there's a teensy bit of kernel support required) and probably
    resulting minor changes in some system header files.

    *That's* why you need to run through the source upgrade procedure that
    Maxim mentioned.

    Bruce.
