A binary package of pkg_install _can_ be created, provided one is
willing to make this small adjustment to the pkgsrc Makefile:

There is no problem whatsoever any more with using the resulting binary
package -- it installs over top of the existing one just fine.

Most of the wrinkles go away with this little INSTALL script:

#! /bin/sh
# -*- sh -*-
#
#ident "@(#)$NetBSD"
#

# De-installation of this package is not (supposed to be) possible, so
# to avoid confusion we just remove the record of previous installs
# having been done.

PKGNAME=$1
STAGE=$2

PKGBASE=${PKGNAME%-[0-9]*}

: ${PKG_DBDIR:=/var/db/pkg}

case ${STAGE} in
PRE-INSTALL)
	rm -rf ${PKG_DBDIR}/${PKGBASE}-[0-9]*
	;;
esac
