Couldn't find gmp library after moving perl module
Just an FYI, but trying to "move" modules like this is always going to cause you more pain than it is worth. Even without root ( or su/sudo ) access you can install a modules anywhere you can write files on the filesystem. Just install the module as you would normally, but give it a PREFIX of some location you have write access to, such as $HOME.
You will then need to just 'use lib' that location and you can avoid situations like this.
