Changing environment variables (env, csh, bash)

I just install BackupPC. The perl install script complains that my environment variable LANG is set to en_US.UTF-8 and that it should be en_US. This setting is specificed in RedHat 9 Linux in the file /etc/sysconfig/i18n. To check what is the current value of the LANG variable type echo $LANG.
