Thanks.  I ended up doing it this way, though with only one loop in 
src_install(), which seems to be a bit more efficient and shorter:


LANGUAGES="de"
for i in ${LANGUAGES}; do
	IUSE="${IUSE} linguas_${i}"
done

src_install()
#...
insinto "${GAMES_DATADIR}/${PN}/i18n"
for i in ${LANGUAGES}; do
	if has ${i} ${LINGUAS}; then
		doins "${PN}_${i}.qm" || die #...
	fi
done


In this case, LANGUAGES must not include "en" though, since there's no 
${PN}_en.qm file (English is built-in).  I'm not sure if the following 
would be better though, in case a user puts linguas_<language> in USE 
instead of <language> in LINGUAS:

   if has linguas_${i} ${USE}; then

But I suppose it would be the user's fault if he/she does that? :P
