how do I tell ports that perl5.8 should never be installed?

Arrgh.  This is so nearly workable.  Unfortunately, -M or -S don't play
nicely with options like -r or -v -- seems you're meant to have local
copies of all of the dependencies already downloaded and in a directory
on $PKG_PATH in that case.

Given that, then this script will reject any attempt to install a pkg
that depends on perl-5.8:

#!/bin/sh

PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin ;
export PATH
IFS=' 	
' ; export IFS
umask 022

reject='^@pkgdep perl-5.8'

TMPFILE=$(mktemp -t mypkgadd) || exit 1
trap "rm $TMPFILE" KILL HUP EXIT

if pkg_add -M ${1+$@} | sed -n -e '/^\/var\/tmp\/instmp/,$p' | \
    tee $TMPFILE | grep "$reject" 2>&1 >/dev/null ; then
    echo "Error: found forbidden package dependency $reject"
    exit 1
fi

pkg_add -S < $TMPFILE && rm -rf $( head -1 $TMPFILE )

#
# That's All Folks!
#

Now, the only missing bit is 'pkg_add -r -S' not fetching dependency
pkgs from the remote  site.  Also options like -r and -v seem to cause
bogons to be emitted to stdout which screws up the -M action, but that
has been worked around.

	Cheers,

	Matthew
