You can install the Cava::Packager utilities into a Perl installation from the application File menu:
Cava Packager will attempt to install using first, PPM if present, and then ExtUtils::Install directly. Either of these options may fail for a number of reasons. For example, you may be running Cava Packager as a user without write permissions for the target Perl installation directories. If the installation fails, you can install the code manually. You can export a standard distribution from the Tools Menu.
