Ubuntu on Xen – locale

Just got a dev box setup on a xen’d version of ubuntu and was getting the following errors when trying to run perl:

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

Our admin did a “locale-gen en_US.UTF-8” and I’m good to go now.
