[Alug] locale

Hello, Ive had this problem since installing Debian (potato), having no success in fixing it.. Its an annoyance more than anything: perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LANGUAGE = (unset), LC_ALL = (unset), LANG = "en_UK" are supported and installed on your system. perl: warning: Falling back to the standard locale ("C"). Looking around for help, a few people mention running 'locale-gen'. I dont have this on my system, should I? Any other ideas would be appreciated, thanks Andrew.
