[David Felipe Arias Ochoa]

tengo este problema con perl como lo puedo arragler, siempre que instalo
algo me muestra error
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
 LANGUAGE = (unset),
 LC_ALL = (unset),
 LANG = "es_ES.ISO-8859-1"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
