Perl locale

[Theta]

Hi guys,

Whenever I run a Perl program or Perl itself, I see this warning message:

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
        LC_ALL = (unset),
        LC_CTYPE = "en_US.UTF-8",
        LANG = (unset)
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

I read through this page. “ls /usr/share/locale” does not exactly list en_US, but it does display en_US.ISO8859-1, en_US.ISO8859-15, and en_US.UTF-8. Running “env LC_ALL=en_US.UTF-8 perl” makes little difference:

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
        LC_ALL = en_US.UTF-8,
        LC_CTYPE = "en_US.UTF-8",
        LANG = (unset)
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

Running “env PERL_BADLANG=0 perl” does solve the problem, but I have a strong feeling that’s not the right way to go about it…
