Right, this is a latin1 locale and the whole compiler was created with
this setting.

I think "ghc-pkg upate - ..." creates the latin1 file.

(I've some latin1 source files that need this setting.)

The LANGUAGE variable is properly a left-over typing error and not
relevant. And "LC_ALL" does not seem to take precedence over LANG on my
(SuSE) system.

It is not sufficient for me to reinstall this package with this utf8
setting. (I think ghc-pkg needs to be fixed or maybe recompiled under utf8.)
