Bryan Christianson of whatroute.net figured this one out. Here is
the fix in case anyone needs it.

There were a couple of problems I found with the source
1. <sys/pcap.h> needs to be included before <pcap.h> in
libpcap_stuff.c
2. the configure script generates systype.h which defines the OS to
be
#define OSTYPE_DARWIN
This type had to be added to tests in sendip.c and ars.c to
activate the weird host-order fields in the raw packet. The code was there
to do that, but OSTYPE_DARWIN was falling thru and generating the more
usual network order for the 2 affected fields.
That is, in libpcap_stuff.c change:
#include <pcap.h>
#include <net/bpf.h>
to:
#include <net/bpf.h>
#include <pcap.h>
In ars.c
#if defined OSTYPE_FREEBSD || defined OSTYPE_NETBSD || defined OSTYPE_BSDI
ip->tot_len = ntohs(ip->tot_len);
ip->frag_off = ntohs(ip->frag_off);
needs to be
#if defined OSTYPE_DARWIN || defined OSTYPE_FREEBSD || defined
OSTYPE_NETBSD || defined OSTYPE_BSDI
ip->tot_len = ntohs(ip->tot_len);
ip->frag_off = ntohs(ip->frag_off);
In sendip.c
#if defined OSTYPE_FREEBSD || defined OSTYPE_NETBSD || defined OSTYPE_BSDI
/* FreeBSD */
/* NetBSD */
ip->tot_len = packetsize;
needs to be
#if defined OSTYPE_DARWIN || OSTYPE_FREEBSD || defined OSTYPE_NETBSD
|| defined OSTYPE_BSDI
/* FreeBSD */
/* NetBSD */
ip->tot_len = packetsize;
and
#if defined OSTYPE_FREEBSD || defined OSTYPE_NETBSD | defined OSTYPE_BSDI
/* FreeBSD */
/* NetBSD */
ip->frag_off |= more_fragments;
ip->frag_off |= fragoff >> 3;
needs to be
#if defined OSTYPE_DARWIN || OSTYPE_FREEBSD || defined OSTYPE_NETBSD
| defined OSTYPE_BSDI
/* FreeBSD */
/* NetBSD */
ip->frag_off |= more_fragments;
ip->frag_off |= fragoff >> 3;

I've compiled hping2 rc3 (http://www.hping.org/) on an Intel box
(10.4.6, Xcode 2.3) and I get this error when running it:
[send_ip] sendto: Invalid argument
If I run it with ktrace, I get this:
1704 hping2 CALL sendto(0x4,0x5004d0,0x28,0,0x152d0,0x10)
1704 hping2 RET sendto -1 errno 22 Invalid argument
1704 hping2 CALL writev(0x2,0xbffff2b0,0x4)
1704 hping2 GIO fd 2 wrote 35 bytes
"[send_ip] sendto: Invalid argument
"
