Adding a perl modul to perl - Does someone know how to do this?

Hi all,
is there anyone who tried successfully adding perl modules like for instance XML/Simple.pm to the perl installation on a My Cloud Mirror Gen2?

The standard procedure, I used on my old My Book World Edition II successfully, does not work on the GEN2.

I used the sshd user, but I do not know the root credentials.

Can someone advice?

Thanks
Peter
