Hmm, in which order are files loaded? Having qw( en ) in config.pl and qw( en en_DW ) in config-local.pl only works if config.pl is loaded first, but IIRC it relies on variables set in config-local.pl for some of the variables it sets, so that wouldn't work. Alternate solution would be to remove it entirely from config.pl and have something in (IIRC) cgi-bin/ljdefaults.pl along the lines of @LANGS = qw( en ) unless @LANGS;
