[horde] cant get rid of "Some of Horde's configuration files are missing"

[Andrew Cook]

here's /usr/www/horde/config:

-rw-r--r--    1 root     root         8449 Nov  3 04:17 horde.php
-rw-r--r--    1 root     root         4205 Nov  3 04:17 html.php
-rw-r--r--    1 root     root        20013 Nov  3 04:17 lang.php
-rw-r--r--    1 root     root         9078 Nov  3 04:17 mime_drivers.php
-rw-r--r--    1 root     root         5184 Nov  3 04:17 mime_mapping.php
-rw-r--r--    1 root     root          140 Nov  3 04:17 motd.php
-rw-r--r--    1 root     root         1159 Nov  3 04:17 prefs.php
-rw-r--r--    1 root     root         8477 Nov  3 04:17 registry.php

everything looks fine, yet horde's index.php still returns that it doesnt
see them.
am I not seeing somethin here?
httpd runs as user 'www'... i tried changing the ownerships of the config
files to match, no effect.
