Короткий шлях: набрати "man /повний/шлях/до/файлу" або натиснути F3 в mc на файлі.
Довгий шлях: яке у вас середовище (ОС-ка, версія man, самі компілювали чи взяли готовий пакети).
man враховує змінну LANG при пошуку довідки. Можна скористатися "strace -e trace=file -o trace.log man manpage" для того щоб побачити де він шукає файли.
Напр. у мене man шукає український переклад в таких каталогах:
cat trace.log | grep /uk

Можна запустити його під ddd (не забудьте поставити пакет man-debuginfo якщо у вас Федора) і подивитися, що там у ньому твориться.
