perl locale

[MaD dUCK <madduck@madduck.net>]

hey guys,
whenever i use perl (rename, apt-get/dpkg, anything), i get

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
        LANGUAGE = (unset),
        LC_ALL = (unset),
        LANG = "en"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

this is really annoying and i know way to little about perl so as to
be able to fix this myself. please please ... any tips?
