Future releases of libpcap probably won't install <net/bpf.h>, so we

shouldn't require it to exist.  Instead, as we're already checking
whether we can find <pcap.h> (which is the only thing we actually
include - we rely on it to include whatever BPF headers are necessary),
we print the big "are you sure you installed the development package?"
message if we don't find "pcap.h".
