The author of vdradmin-am integrated the patch to the make script, which generates utf-8 locales out of the existing ones. Please generate them in the emerge script, at least depending on a USE flag like "unicode", instead of echoing "no need to compile". Patch attached.
Created attachment 99692 [details, diff] patch to vdradmin-am-3.4.7.ebuild which adds generating utf-8 locales
