Hiya.

I've been working on a web front-end to aggregate multiple servers'
package update requirements as well.  I'll probably have it ready to
present in another few weeks, if ${DAYJOB} doesn't get in the way.

Use more quotes.

  REPORT = "`pkg_version -v`"

will protect the newlines.

If you feel adventurous, you could to try something like this:

  tmpfile=/tmp/`basename $0`.$$
  trap "rm -f $tmpfile $tmpfile.?" 0 1 2 3 5 15
  pkg_version -v | while read package status text; do
    echo "$package $text" >> $tmpfile."$status"
  done

Now you have tempfiles with package lists for the various stati, which
you can parse as you see fit.

Note that you may get better (i.e. more useful) mileage out of something
like:

  pkg_version -vL=

which will show you only what needs to be updated.
