[Jailkit-users] jk_init error: "sh: ldconfig: command not found"

[Giuliano Catrambone (CatraSoftware)]

Hi all,
    I installed jailkit on a RH5 machine, but when I run the command:

        /usr/sbin/jk_init -j /app/FTPRepository/jailroot jk_lsh

    after it copied a lot of files, I got the error:

...
Creating symlink /app/FTPRepository/jailroot/lib/libpthread.so.0 to libpthread-2.5.so
Copying /lib/libpthread-2.5.so to /app/FTPRepository/jailroot/lib/libpthread-2.5.so
Copying /etc/jailkit/jk_lsh.ini to /app/FTPRepository/jailroot/etc/jailkit/jk_lsh.ini
sh: ldconfig: command not found

    I look for ldconfig in my RH5 machine but it seems this command is not present.
    Do I have to install something?

    Could you help me?
    Thanks in advance
        giu
