hypenation in tetex

[Igor Mozetic <igor.mozetic@uni-mb.si>]

How does one change hypenation in potato tetex ??
I've run texconfig and changed the /etc/texmf/language.dat - no effect.
When I run Latex I still get the original hypenation:

This is TeX, Version 3.14159 (Web2C 7.3.1)
(avt.tex
LaTeX2e <1998/12/01> patch level 1
Babel <v3.6x> and hyphenation patterns for american, french, german, ngerman, n
ohyphenation, loaded.

Package babel Warning: No hyphenation patterns were loaded for
(babel)                the language `Russian'
(babel)                I will use the patterns loaded for \language=0 instead.
