First, thank you for replying so fast !
/etc/rc.d/ldconfig is a /bin/sh script, and I can't run /bin/sh in this chroot.
Same errors.

After that command, the shared libraries are found, but ld refers to /mnt :
# ldconfig -rf /mnt/var/run/ld-elf.so.hints
/mnt/var/run/ld-elf.so.hints:
search directories: /mnt/lib:/mnt/usr/lib
0:-lc.7 => /mnt/lib/libc.so.7
1:-lcrypt.4 => /mnt/lib/libcrypt.so.4
[...]
And then when trying to chroot, still the same problem. I also can't launch
ldconfig in the jail :
# chroot /mnt/ /sbin/ldconfig -32 -s -f /var/run/ld-elf.so.hints /lib /usr/lib
ELF interpreter /libexec/ld-elf.so.1 not found
Abandon
Cheers,
Olivier
