You have to set locale *before* installing gettext. Also on Windows, you
have to check if LANG environment is set and is usable (if not, you can
set it for current process).

    if os.name == 'nt':
        # windows hack for locale setting
        lang = os.getenv('LANG')
        if lang is None:
            default_lang, default_enc = locale.getdefaultlocale()
            if default_lang:
                lang = default_lang
        if lang:
            os.environ['LANG'] = lang

Then you should install gettext.
