+Before installing this module, you should append C<perl-gcpanp> to your F</etc/portage/categories> file.
+
+You have two ways for installing this module :
+
+=over 4
+
+=item *
+
+Use the perl overlay located at L<http://git.overlays.gentoo.org/gitweb/?p=proj/perl-overlay.git>.
+It contains an ebuild for L<CPANPLUS::Dist::Gentoo>.
+
+=item *
+
+Bootstrap an ebuild for L<CPANPLUS::Dist::Gentoo> using itself.
+Note that if your Gentoo system C<perl> is C<5.8.x>, L<CPANPLUS> and its dependencies are not installed and not even available in the main portage tree.
+So you need to bootstrap them as well.
+
+First, fetch tarballs for L<CPANPLUS> and L<CPANPLUS::Dist::Gentoo> :
+
+    $ cd /tmp
+    $ wget http://search.cpan.org/CPAN/authors/id/K/KA/KANE/CPANPLUS-0.88.tar.gz
+    $ wget http://search.cpan.org/CPAN/authors/id/V/VP/VPIT/CPANPLUS-Dist-Gentoo-0.08.tar.gz
+
+Log in as root and unpack them in e.g. your home directory :
+
+    # cd
+    # tar xzf /tmp/CPANPLUS-0.88.tar.gz
+    # tar xzf /tmp/CPANPLUS-Dist-Gentoo-0.08.tar.gz
+
+Set up environment variables so that the toolchain is temporarily available :
+
+    # export OLDPATH=$PATH
+    # export PATH=/root/CPANPLUS-Dist-Gentoo-0.08/bin:$PATH
+    # export PERL5LIB=/root/CPANPLUS-Dist-Gentoo-0.08/blib/lib:/root/CPANPLUS-0.88/lib:/root/CPANPLUS-0.88/inc/bundle
+
+Make sure you don't have an old C<.cpanplus> configuration visible :
+
+    # [ -d /root/.cpanplus ] && mv /root/.cpanplus{,.bak}
+
+Bootstrap L<CPANPLUS> :
+
+    # cd /root/CPANPLUS-Dist-Gentoo-0.08
+    # samples/g-cpanp CPANPLUS
+
+Reset the environment :
+
+    # export PATH=$OLDPATH
+    # unset PERL5LIB OLDPATH
+
+Emerge L<CPANPLUS> with the ebuilds you've just generated :
+
+    # emerge -tv CPANPLUS
+
+As of september 2009, C<podlators> and C<ExtUtils-MakeMaker> may fail to emerge due to collisions.
+You can work around this by disabling the C<protect-owned> C<FEATURE> for them :
+
+    # FEATURES="-protect-owned" emerge podlators
+    # FEATURES="-protect-owned" emerge ExtUtils-MakeMaker
+
+You may need to run each of these commands two times for them to succeed.
+
+At this point, you can bootstrap L<CPANPLUS::Dist::Gentoo> using the system L<CPANPLUS> :
+
+    # PERL5LIB=/root/CPANPLUS-Dist-Gentoo-0.08/blib/lib samples/g-cpanp CPANPLUS::Dist::Gentoo
+    # emerge -tv CPANPLUS-Dist-Gentoo
