app-office/libreoffice-4.1.3.1 appeared with language files at http://download.documentfoundation.org/libreoffice/src/4.1.3/ since 2013-10-11 as rc I think.
Sorry we don't provide all rc candidates as it takes hell to compile. We usually put up only the last one (or one extra if somehting goes wrong). But you can do it localy yourself to just cp the files if you want to try it.
