Messing with the system Perl is a very bad idea. Depending on your OS, you could hose your computer. And if I'm following, it won't fix your real problem even if it works. Let's backup.
You seem to be talking about two different setups. Your home computer/server and your host server. Is this right?
Installing things in your system on your computer will have no effect on a remote host/server. Can you upload files/directories to your host *outside* your cgi-bin and your www-root?
Do you have a shell account to ssh into your host? Or is it pure (S)FTP?
