Found out the problem... Had to:
1. install glibc-i18n-2.3.2-noarch-1.tgz
2. edit /etc/profile.d/lang.sh
Look in /usr/share/i18n/locales for supported languages. If you want German language support you change the file /etc/prodile.d/lang.sh so it looks like this 'export LANG=de_DE'
Now Amigo has internationalization support.
