In ActivePerl, "ppm" installs a package from the Internet, "ppm install x.ppd" installs from a ppd file, but most CPAN packages are distributed as .tar.gz
How do you supply modules to a machine running ActivePerl that doesn't have an Internet connection? ("make" will probably not be available.)
Update: an Internet connection can be used to download files and transfer them to the machine with a USB key, etc.
