... I'm not missing anything I know of, but the build fails during 
pcap-util.c, because pcap_if_t is undefined.

Moreover, I can't find the pcap_if_t definition, in /usr/include, in 
Apple's libpcap sources, or in the tcpdump.org tcpdump-0.6.2 tarball 
(this is the version OS X 10.3.2 uses) or in the ethereal soures.
Where can I find pcap_if_t?
Please pardon any possible operator error, and please don't hesitate to 
let me know if this sort of traffic should be on another list.
