I did this a looong while back :
$=> cat perl5.bash
#!/macports/bin/bash
#
# change these to reflect your installation:
#
# prefix : where you have installed macports
# macportsRoot : where you want to store the modifed Portfiles
#
# ${1} :: type of conversion (hard|soft) (default:soft)
# ${2} :: old version of Perl5 (default: 12)
# ${3} :: new version of Perl5 (default: 16)
#
declare prefix='/macports'
declare macportsRoot='/Volumes/Bjarne/WebServer/MacPorts/portfiles'
declare type=${1:-soft}
declare -i versionOld=${2:-12}
declare -i versionNew=${3:-16}
# don't change this
declare
rsyncMacportsOrg='/var/macports/sources/rsync.macports.org/release/tarballs/ports'
mkdir -pv ${macportsRoot}
declare -i counter=0
declare -i totalPorts=$( port -q list | wc -l )
declare -i portrev
#
# this time we're only interested in perl5.12
#
cd "${macportsRoot}"
#
# find all the ports that are dependent on perl5.${version}
# or p5.${version}-<something>
#
while read portname[0] portname[1] portname[2]
do
(( counter++ ))
printf "\r[ %5i | %5i ] %-50s" ${counter} ${totalPorts} ${portname[2]}
fundet=$( \
grep -E -e "(perl5.${version}|p5.${version})" $(port file
${portname[0]}) \
| wc -l )
if [ ${fundet} -gt 0 ]
then
#
# copy the Portfile
#
echo ''
mkdir -p ${portname[2]}
cd ${portname[2]}
cp $(port file ${portname[0]}) 'Portfile.orig'
#
# splice the PortGroup command into the Portfile
#
portrev=$( grep -i "PortGroup.*perl5" 'Portfile.orig' | wc -l )
if [ ${portrev} -eq 0 ]
then
sed -En -e "1,/^PortSystem/p" 'Portfile.orig' \
> 'Portfile'
echo -e "PortGroup perl5 1.0" \
>> 'Portfile'
sed -E -e "1,/^PortSystem/d" 'Portfile.orig' \

else
cp 'Portfile.orig' 'Portfile'
fi
#

'Portfile'
esac
#
# create *.diff files for all the copied Portfiles
#
rm 'patch-Portfile.diff' 2>/dev/null
diff -u \
$( port file ${portname[0]} ) \
'Portfile' \
> 'patch-Portfile.diff'
cd ${OLDPWD}
fi
done < <( port list )
printf "\r[ %5i | %5i ] %-50s\n" ${counter} ${totalPorts} '*** FINISHED ***'
needs to be modified for the current situation, but it's a starting
point ;-)
