You can get PORTDIR with:
paludis --configuration-variable gentoo location

AFAIK, PORTDIR_OVERLAY is more tricky:
for r in $(paludis --list-repositories | sed -e "s/^*\ //g") ; do
    if [[ $(paludis --configuration-variable ${r} format) = "ebuild" ]] ; then
        paludis --configuration-variable ${r} location
    fi
done
