That seems rather strange, to me at least. Why wait for a specific
ebuild when you can install in /usr/local (and /usr/local *is* part of
the "gentoo way" ;)

Anyhow ..

off the top of my head, i would do something like (oneliner):

zsh% =ls -d /usr/portage/*([^distfiles][^profiles][^scripts][^packages])**/*
>| /tmp/ports-list ; emerge sync && =ls -d \
/usr/portage/*([^distfiles][^profiles][^scripts][^packages])**/* \
>| /tmp/ports-list-new | comm -1 -3 /tmp/ports-list /tmp/ports-list-new \
>| /tmp/new_in_portage ; less /tmp/new_in_portage

i guess this could be done with bash also (if we set extglob). Here's a
short script (limited testing).

#!/bin/bash
# watznu.sh
shopt -s extglob

function ask()
{
echo -n "$@" '[y/n] '; read answer
    case "$answer" in
        y*|Y*) return 0
        ;;
        *) return 1
        ;;
esac
}

lsportage="ls -d /usr/portage/*([^distfiles][^profiles][^scripts][^packages])**/*"

$lsportage >|/tmp/ports-list

emerge sync || exit

$lsportage >|/tmp/ports-list-new

comm -1 -3 /tmp/ports-list /tmp/ports-list-new >|/tmp/new_in_portage
rm -f /tmp/ports-list*

if [ -s /tmp/new_in_portage ]; then
    echo "There are new ports in portage"
    echo "Do you wish to see what these new ports are?"
    ask && $PAGER /tmp/new_in_portage
else
    echo "Nothing new in portage"
    rm -f /tmp/new_in_portage
fi

# EOF
