Greetings Joseph,
I'm not sure if I follow you exactly. But if I understand you correctly;
you're looking to create a pkg-plist file via make makeplist, and your
port doesn't actually build anything (contains installation files?).
You need a minimum of
Makefile
distindo
pkg-descr
in your port directory.
for a minimum Makefile for what I understand your port to do. The
following should work:
# $FreeBSD$

PORTNAME=
PORTVERSION=
CATEGORIES=
MASTER_SITES=

MAINTAINER=
COMMENT=

LICENSE=
LICENSE_FILE=	(if necessary)

USES=		tar:txz
NO_BUILD=	yes

.include <bsd.port.mk>

note the key here is NO_BUILD
you mention your distfile uses tar(1) and xz(1). The above example
assumes the extension name is .txz ; adjust as needed. You will
(of couse) need to fill all the empty fields as needed, as well as
add || subtract them, as needed.

Hope this helps.
