I'm having a similar problem.
I've compiled aMule from the sources and I don't get the german version (on Debian Etch) :-(
The output of my locale is:
LANG=de_DE@euro
LANGUAGE=de_DE:de:en_GB:en
LC_CTYPE="de_DE@euro"
LC_NUMERIC="de_DE@euro"
LC_TIME="de_DE@euro"
LC_COLLATE="de_DE@euro"
LC_MONETARY="de_DE@euro"
LC_MESSAGES="de_DE@euro"
LC_PAPER="de_DE@euro"
LC_NAME="de_DE@euro"
LC_ADDRESS="de_DE@euro"
LC_TELEPHONE="de_DE@euro"
LC_MEASUREMENT="de_DE@euro"
LC_IDENTIFICATION="de_DE@euro"
LC_ALL=
I do have a "amule.mo" in "/usr/local/share/locale/de/LC_MESSAGES"
"gettext" is installed on my system. I can't find "gettext-devel" with apt-cache search ...
Any ideas?
