Anytime I try to use perl I get this message.

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LANG = "en_us"
are supported and installed on your system.


Does anyone know how to fix this.. I have searched google and most of the pages that I found are in spanish and the other ones dont help at all.. I have consulted the man pages but I just dont get it.

Can someone tell me what needs to be done.

Thanks
