Argh. After figuring out what was wrong here, I then realised this was
already fixed in the libpcap0.8 package, just not in this embedded copy
of the library:
--- a/pcap-bpf.c
+++ b/pcap-bpf.c
@@ -31,8 +31,8 @@ static const char rcsid[] _U_ =
#ifdef HAVE_ZEROCOPY_BPF
#include <sys/mman.h>

#include <sys/socket.h>

/*

With that applied, for nping and nmap binaries to then link with the
statically-compiled embedded libpcap, they must also link with -lrt,
which the attached patch takes care of.
Builds successfully on kfreebsd-i386 after that, and appears to work.
While here, I also saw what looked like Microsoft .exe redistributables
in the source tarball / Git repository?
