Problems with 5.6.0 in Mandrake

[mattman]

I'm using a combo roll-your-own/Mandrake 7.2 Linux distribution, with perl-5.6.0-17mdk and associated packages installed. My problem is this:

==========
matt@mattman ~ > perl -v
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
        LANGUAGE = "en_US:en",
        LC_ALL = (unset),
        LC_MONETARY = "en_US",
        LC_CTYPE = "en_US",
        LC_NUMERIC = "en_US",
        LC_MESSAGES = "en_US",
        LC_TIME = "en_US",
        LC_COLLATE = "en_US",
        LANG = "en"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

I can't seem to figure out how to set the locale and stuff to get rid of these messages. Using the set command doesn't list them, but setenv does. I'm using tcsh, by the way. Same thing happens if I use bash. Anybody have any answers, or should I just rebuild from source?
