Importing devel/p5-pip 1.16 as dependency of import of Perl Application
Development and Refactoring Environment.

The pip ("Perl Installation Program") console application is used to install
Perl distributions in a wide variety of formats, both from CPAN and from
external third-party locations, while supporting module dependencies that go
across the boundary from third-party to CPAN.

Using pip you can install CPAN modules, arbitrary tarballs from both the
local file-system or across the internet from arbitrary URIs.
