I rebuilt and reinstalled both the kernel and world. I can now verify
that I have BPF support as 'ls /dev/bpf0' returns correctly (my
understanding is that FreeBSD 5.x uses devfs and creates devices on
demand).

wackamole still behaves the same:
# wackamole -d
socket: Protocol not supported

I toyed with gdb a bit and tracked the failing socket() function call
down to ife-bpf.c:27:

27 	if((_if_sock = socket (AF_INET, socket_type, htons(ETH_P_ALL))) == -1) {
28          perror ("socket");
29          exit (EXIT_FAILURE);
30        }
