The variable LINGUAS is neither in make.conf.example nor in man make.conf documented. Is it still supported? The localisation guide still uses LINGUAS: http://www.gentoo.org/doc/en/guide-localization.xml#doc_chap3 need to update manpage and /or make.conf.example
Of course it is support. It has nothing to do w/ portage, as such the documentation doesn't belong there. *** This bug has been marked as a duplicate of bug 97746 ***
