You seem to be missing definitions of struct sockaddr, so probably
sys/socket.h is needed.

Here it looks like you're missing struct in_addr, which is in
sys/netinet/in.h (and also arpa/inet.h).

Some of these missing parameters are Linux-specific.

As you can see, porting requires some care.  It's not only a matter of
including different headers; there are some other differences that may
require patches, and we won't be able to go through this step-by-step
on the list.  You can see what FreeBSD headers a similar FreeBSD
application needs by looking at src/usr.sbin/arp, and you can get some
help with the Linux->FreeBSD part by looking at /sys/compat/linux,

http://svn.freebsd.org/viewvc/base/projects/ofed/head/sys/ofed/include/

and

http://fxr.watson.org/

; and you might be able to cheat a bit by using a compatibility layer
like devel/gnulib, but you're going to have to go through this
carefully on your own.
