  Here's a little script (I call it "mkpkg") that I use to build package
files from already-installed packages.  I find it useful mainly for backing
up a package before deleting it in preparation for installing an updated
version.

#! /bin/sh
#
# Construct a binary package entirely from an installed package
#

pkg_name=$1
PKG_DBDIR=/var/db/pkg
pkg_info -e $pkg_name || { echo "$pkg_name is not installed" && exit 1; }
PREFIX=$(pkg_info -q -p $pkg_name | sed -e 's/^@cwd //')

ARGS="-v -p ${PREFIX}"

file=${PKG_DBDIR}/${pkg_name}/+COMMENT
if [ -f ${file} ]; then ARGS="${ARGS} -c ${file}"; fi

file=${PKG_DBDIR}/${pkg_name}/+DESC
if [ -f ${file} ]; then ARGS="${ARGS} -d ${file}"; fi

file=${PKG_DBDIR}/${pkg_name}/+CONTENTS
if [ -f ${file} ]; then ARGS="${ARGS} -f ${file}"; fi

file=${PKG_DBDIR}/${pkg_name}/+INSTALL
if [ -f ${file} ]; then ARGS="${ARGS} -i ${file}"; fi

file=${PKG_DBDIR}/${pkg_name}/+DEINSTALL
if [ -f ${file} ]; then ARGS="${ARGS} -k ${file}"; fi

file=${PKG_DBDIR}/${pkg_name}/+DISPLAY
if [ -f ${file} ]; then ARGS="${ARGS} -D ${file}"; fi

file=${PKG_DBDIR}/${pkg_name}/+MTREE_DIRS
if [ -f ${file} ]; then ARGS="${ARGS} -m ${file}"; fi

pkg_create ${ARGS} ./$pkg_name.tgz
