building sysutils/dd_rescue on FreeBSD 8.x?

[Torfinn Ingolfsen]

Hello,
Does anyone know how to build sysutils/dd_rescue on FreeBSD 8.4-stable?
Specifically this one:
tingo at kg-core1$ uname -a
FreeBSD kg-core1.kg4.no 8.4-STABLE FreeBSD 8.4-STABLE #1 r266590: Fri
May 23 20:23:35 CEST 2014
root at kg-core1.kg4.no:/usr/obj/usr/src/sys/GENERIC  amd64

Latest ports tree (updated today).
I added
MAKE_ARGS+= CFLAGS_OPT="-D__WORDSIZE=64"
CFLAGS+=    -D__WORDSIZE=64
to the ports Makefile
but the port still bombs out:
