(mostly a note to myself) app-office/auto-multiple-choice should use L10N. Right now it offers templates etc in the variants "AR", "DE", "EN", "FR", "JP". However, "FR" reqires LaTeX with french style files and "JP" requires texlive-core with cjk support... Making the ebuild only install required languages might cut down the number of dependencies.
To add a couple of bits to this: - even with cjk support added, I couldn't get the documentation to build without modifications. It looks like it needs fonts (IPAexMicho ?) that I couldn't find in portage. Perhaps they're there and I just couldn't find them, but adding japanese to support to texlive, pulling in cjk-latex, texlive-langcjk and texlive-langjapanese and texlive-langcjk didn't pull in the needed fonts. However, I was able to remove the japanese documentation by: a) removing the reference to doc/doc-xhtml-site.ja.xsl in the top-level Makefile and b) "rm doc/*.ja.*" - as is, the ebuild makes portage want to pull in texlive-2012. This appears to be due to the fact it asks for doc and dvipdfm useflags that haven't existed since texlive-2012. After removing those two flags from the requirements for texlive, the dependencies work out ok. Perhaps a dependency on ghostscript-gpl should be added though, as it provides dvipdf now. - I think a dependency on pdftk is also necessary. Thanks so much for bringing this in, I use it extensively!
Most of this should be fixed in -r1, please test.
