Configuring the ntm-ltx? packages

You have installed LaTeX2e with babel. There is a file 
/usr/lib/texmf/tex/latex/cfg/language.dat which defines which
hyphenation tables are loaded into LaTeX2e. It is preconfigured with
ukenglish, usaenglish, german and swedish. If you want to change this
you have to edit this file. Please do not load more hyphenation tables
as you need since TeX's capacity is limited. I think you will get in
trouble if you load more than 4 tables, but this depends on the size of
them.

Since you have installed LaTeX2e you might also want to recreate the
LaTeX2e format file. You should do this especially if you did not install
all LaTeX2e packages or if you changed language.dat from babel.
