[Fedora TeX Live] hyphenation in texlive 2011?

[pip]

Thank you, Mojca.

I guess it should be the same. Jindrich will correct me if I'm wrong. Or make corrections if something's wrong in Fedora.

I have texlive-hyph-utf8 installed, indeed. And there are croatian (HR) hyph rules.

texlive-collection-langcroatian is also here

This seems not to be the case. There's nothing new written to /usr/share/texlive/texmf/tex/generic/config/language.dat
Jindrich, can you help?

Ah... this is a bit inconvenient, and rather unknown option. I'd expect ngerman (croatian as well) point to the latest version of the rules. As a user of LyX, I think most of the people would expect this too --- that all is handled only with(in) babel.
Is there a systematic way of doing this in TeX Live?
