Go2Linux shows you how to fix the "LC_CTYPE to default locale: No such file or directory" problem

Today I have installed a new server at linode, and I put Arch Linux on it.
I've also installed LAMP on it, but as soon as I tried to start Apache I run into some errors.
LCCTYPE: cannot change locale (enUS.utf8): No such file or directory
These are the errors I found while trying to start Apache.
