Like PGXN, it formally does not care, but its implementation expects source code distributions what will be built and installed by users. Note that the vast majority of those modules, -- even pure Perl modules -- are built with make.

So users typically get their Perl modules in one of these ways:

1. As binaries from their distribution’s package manager. These tend to be updated manually by volunteers and not integrated into CPAN, though there are solutions such as [rpmcpan](https://github.com/iovation/rpmcpan) and [PPM](http://www.activestate.com/activeperl/ppm-perl-modules) which do regular distro package builds.

2. As source code from CPAN, from which they are compiled (when necessary), built, and installed by the user or a build system such as [Homebrew](https://brew.sh).

Best,

David
