Well, that explaines it right there. It wasn't installed properly, because 
every installed port should have a +CONTENTS file.
You can grab the files from 'pkgdb.db' like Andrew suggested, but I personally 
wouldn't trust those if portupgrade was the one that did this in the first 
place.
This is where daily backups rock :).

If your /usr/ports/INDEX-6 (or -7) is in sync with your installed packages, 
then maybe the following script will work. It worked for me testing it, but I 
can't guarentee it will work in all cases.

If you're on FreeBSD 6, change INDEXFILE to /usr/ports/INDEX-6. Rest should 
work without changes.

#!/bin/sh


INDEXFILE='/usr/ports/INDEX-7'
for dir in /var/db/pkg/*; do
    if test ! -e ${dir}/+CONTENTS -a -d ${dir}; then
        pkgname=${dir##*pkg/}
        echo "Restoring ${pkgname}"
        IDX=$(grep "^${pkgname}|" ${INDEXFILE} 2>/dev/null)
        if test -z "${IDX}"; then
            echo "Failed: cannot find ${pkgname} in ${INDEXFILE}"
        else
            _origin=${IDX#*|}
            origin=${_origin%%|*}
            echo "---> ${origin}"
            cd ${origin}
            mv ${dir} /tmp/
            make -DFORCE_PKG_REGISTER generate-plist fake-pkg
            for file in /tmp/${pkgname}/*; do
                f=${file##*/}
                if test ! -f ${dir}/${f}; then
                    echo "--> Restoring ${pkgname}/${f}"
                    mv ${file} ${dir}/
                fi
            done
        fi
    fi
done

Problem with today's modular software: they start with the modules
    and never get to the software part.
