locale

Hi fellow gentoo user,

Please help fix my locale issue with systemd.

Some programs do not start because of his (firefox/porthole) and also emerge does give me error of wrong locale.

I used sytemd to set the locale to ENGLISCH (en) however, this seems not to be reflected by the locale setting.

orion manuel # emerge wine
setlocale: unsupported locale setting
