I18N: Operating system doesn't support locale "en_US"

[Malcolm Kay]

On starting openoffice.org-2.4.3 I immediately get the warning/error:
  I18N: Operating system doesn't support locale "en_US"

Since my locale is not US why should openoffice care?

In any case, what does it want in order to believe that
the operating system does support locale "en_US"?

%locate en_US | grep '^/usr/.*\(locale\|nls\|i18n\|I18N\)/en_US[^/]*$'

Is there a way to satisfy openoffice apart from the hack
of redirecting stderr to /dev/null?

Please help or comment,
