SSH locale

Current version:

nas:/var/log# cat /etc/raidiator_version 
RAIDiator!!version=4.2.22,time=1346830413

I wanted to regenerate the locales, since all of them are missing:

nas:/var/log# locale -a
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_COLLATE to default locale: No such file or directory
C
POSIX

Tried to reconfigure locales, but didn't succeed because localedef is indeed not found

nas:/var/log# dpkg-reconfigure locales

Tried to reinstall libc6

nas:/var/log# apt-get install --reinstall libc6
<snip>
Preparing to replace libc6 2.7-18lenny7 (using .../libc6_2.7-18lenny7_i386.deb) ...
Matching libraries: /usr/lib/libm.so.6

A copy of glibc was found in an unexpected directory.
It is not safe to upgrade the C library in this situation;
please remove that copy of the C library and try again.
dpkg: error processing /var/cache/apt/archives/libc6_2.7-18lenny7_i386.deb (--unpack):
<snip>

nas:/var/log# find / -name libm.so.6
/usr/lib/libm.so.6
/lib/libm.so.6

What a mess...
