I would try creating a very simple test script, with the full path and filename hardcoded, etc, just to prove that the unzipper utility will do what you want.

Assuming that it turns out to be incompatible with the host's system, you're going to need to handle the unzipping yourself. Never fear, someone has already done all the hard work for you and put it on CPAN. I'd suggest trying IO::Uncompress::AnyInflate for simple gzip/zip type files.
