errr, just because my name is involved...

% alias ecd
cd $EPREFIX/usr/portage/*-*/!*

I have it as alias, not as function.  If you have a function you can
(and should) actually do more magic, like:

ecd() {
	[[ -z $1 ]] && return
	p=( $(echo /usr/portage/*/$1) )
	if [[ ${p[*]} == *"/*/"* ]] ; then
		echo "no such package: $1" > /dev/stderr
	elif [[ ${#p[@]} > 1 ]] ; then
		echo "multiple options: ${p[*]}"
	else
		# we can't handle spaces in the paths here anyway
		cd ${p[*]}
	fi
}

And probably this can be done even better with respect to the glob...
