Sorry, I don't know that webhoster. It's not really a perl question anymore now...

Lucky you it looks like XML::Smart comes with a pure perl XML parser.
You could do either:

1. build the modules locally, then transfer them by FTP - that's a bit tedious because you need a bunch of modules.
2. ask your webhoster to install the module.
3. ask your webhoster to get shell access.
4. find some other webhoster that grants shell access.
