locale

[sm51]

Any one familiar with locales...

I've tried several times to make use
of non-english locales for blackbox, but
everytime blackbox returns an error message
saying it was unable to set locale environment
variables.  I have the lastest locale and libc6
installed, and I belivve spanish is supported.
I've set the LANG=es, and LANG=es_ES, but nothing
seems to work.  On my machine at work however 
bb works fine, is there something else I need to install
so my machine recognizes non-english locales?

thanks
