sharutils offers a message catalog for Japanese EUC locale into /usr/share/locale/ja_JP.EUC which differs from other packages; they use /usr/share/locale/ja
It does not really matter. Apps will fall bacl to the "ja" dir
Apps will fall back to the "ja" dir?? There is no message catalogs in "ja" dir. There displays no messages because they look into /usr/lib/locale/. If you rebuild the package, they says: gcc -c -DLOCALEDIR=\"/usr/lib/locale\" -DHAVE_CONFIG_H -I. -I.. -I../ lib -I../intl -I../intl -O2 -m486 -fno-strength-reduce shar.
Fixed in sharutils-4.2-13
