In GRASS, we are in a transition of changing all relevant fprintf(stdXXX,"...")
to G_message(_("...")) with gettext macro. In the case of the
datum message it's still the old fprintf() without macro.

Sorry for that confusion. It is because we are only half through
with changing all messages to gettext macros. Since GRASS is
huge this is a long lasting task.

Yes, you need to 'make distclean' and 
 ./configure --with-nls ...
to activate the language support.
