39 This module is a CPANPLUS backend that recursively generates Gentoo ebuilds for a given package in the specified overlay (defaults to C</usr/local/portage>), update the manifest, and even emerge it (together with its dependencies) if the user requires it. You need write permissions on the directory where Gentoo fetches its source files (usually C</usr/portage/distfiles>).
41 The generated ebuilds are placed into the section C<perl-gcpanp>. They favour depending on C<perl-core> or C<dev-perl> rather than C<perl-gcpanp>.
45 After installing this module, you should append C<perl-gcpanp> to your F</etc/portage/categories> file.
49 All the methods are inherited from L<CPANPLUS::Dist::Base>. Please refer to its perldoc for precise information on what's done at each step.
