Assuming you have a shell login to your host, you can always install modules locally - in fact, this is usually a better way to go in any event, because then you can control which version you're using, when to upgrade, etc. And if you switch hosts, just tar up your perl directory and ftp it - you're guaranteed to have the same stuff at the new host. Read the docs for the CPAN module, and check the FAQs on this site for installing locally.
