On macOS, we recommend install and upgrade from the tar or zip
distribution as described above. We recommend installing Xcode and Perl
installation management tool, such as Perlbrew, which can be used to
install, for example,
cpanm
to obtain modules from
CPAN. For more information, see
Section 2.1.2. CPAN. This allows you to
start working with Radiator without modifying the Perl installation that
comes with macOS.
Perl that comes with macOS works with Radiator, but may not have all
the modules your configuration might require.
