Comment #22 on issue 2742 by [email protected]: Patch: Add support for Cyrillic in texinfo.

As far as GUB is concerned, John and I have discussed adding some kind of checks (like "configure") to GUB such that it dies if you don't have the right dependencies. I don't think that a .deb is ideal since some people (like John) run it on Fedora.
