Created attachment 138253 [details, diff] NLS fix This patch utilizes LINGUAS from /etc/make.conf and installes supported languages effectively.
Thank you Petr, for report and fix! Note that you should quote "${I18N}". In other case only first language in LINGUAS will work. With this remark fixed in djvu-3.5.20-r1.
