cd /usr/ports/foo/bar
make
mv /var/db/pkg/bar-x.y.z/+REQUIRED_BY .
pkg_delete bar-a.b.c
make install
mv +REQUIRED_BY /var/db/pkg/bar-d.e.f
port_update.sh bar a.b.c d.e.f

port_update.sh:
---snip---
#!/bin/sh

# Syntax: port_update.sh <progname> <version_old> <version_new>
# yes, I know it's ugly

if [ ! $3  ]; then
  echo "$0 <name> <oldver> <newver>"
  exit 1
fi

for i in `cat /var/db/pkg/${1}-${3}/+REQUIRED_BY`; do
  echo -n "Updating ${i}... "
  perl -npi -e "s:\@pkgdep\ ${1}\-${2}:\@pkgdep\ ${1}\-${3}:g" /var/db/pkg/${i}/+CONTENTS
  echo "done"
done
---snip---

Lazy disclaimer:
 - works for me
 - I think I know what I'm doing here (and what the limitations are
   (e.g. bar == libxyz && libmajorversion(old) !=
   libmajorversion(new))).

Bye,
Alexander.
