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

Just unset all locale related strings and force C locale.
