Aaargh. I vote for setting the reply-to-ist header for all gentoo lists.

Ah okay qmake. I somehow mixed this up with cmake.

This should work but more convenient would be if there is some
configuration switch you can use to define the installed languages.

I use this for appending LINGUAS to IUSE but only because I have seen
this many times in other ebuilds

IUSE="dbus debug kde monolithic +oxygen phonon postgres +server +ssl webkit +X"

LANGS="cs da de fr hu it nb_NO ru sl tr"
for l in ${LANGS}; do
	IUSE="${IUSE} linguas_${l}"
done

Putting it directly in IUSE will also work.
