 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>.
+It contains an ebuild for L<CPANPLUS::Dist::Gentoo> which will most likely be up-to-date given the reactivity of Gentoo's Perl herd.
 
 =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> :
+First, make sure your system C<perl> is C<5.10> or greater, so that the L<CPANPLUS> toolchain is available.
 
-    $ cd /tmp
-    $ wget http://search.cpan.org/CPAN/authors/id/B/BI/BINGOS/CPANPLUS-0.9003.tar.gz
-    $ wget http://search.cpan.org/CPAN/authors/id/V/VP/VPIT/CPANPLUS-Dist-Gentoo-0.10.tar.gz
-
-Log in as root and unpack them in e.g. your home directory :
-
-    # cd
-    # tar xzf /tmp/CPANPLUS-0.9003.tar.gz
-    # tar xzf /tmp/CPANPLUS-Dist-Gentoo-0.10.tar.gz
-
-Set up environment variables so that the toolchain is temporarily available :
-
-    # export OLDPATH=$PATH
-    # export PATH=/root/CPANPLUS-0.9003/bin:$PATH
-    # export PERL5LIB=/root/CPANPLUS-Dist-Gentoo-0.10/blib/lib:/root/CPANPLUS-0.9003/lib:/root/CPANPLUS-0.9003/inc/bundle
+    $ perl -v
+    This is perl 5, version 12, subversion 2 (v5.12.2) built for x86_64-linux
+    ...
 
-Make sure you don't have an old C<.cpanplus> configuration visible :
+C<perl> C<5.12> is the current stable Perl version in Gentoo.
+If you still have C<perl> C<5.8.x>, you can upgrade it by running the following commands as root :
 
-    # [ -d /root/.cpanplus ] && mv /root/.cpanplus{,.bak}
+    # emerge -tv ">=dev-lang/perl-5.10"
+    # perl-cleaner --all
 
-Bootstrap L<CPANPLUS> :
+Then, fetch the L<CPANPLUS::Dist::Gentoo> tarball :
 
-    # cd /root/CPANPLUS-Dist-Gentoo-0.10
-    # samples/g-cpanp CPANPLUS
-
-Reset the environment :
-
-    # export PATH=$OLDPATH
-    # unset PERL5LIB OLDPATH
-
-Emerge L<CPANPLUS> with the ebuilds you've just generated :
+    $ cd /tmp
+    $ wget http://search.cpan.org/CPAN/authors/id/V/VP/VPIT/CPANPLUS-Dist-Gentoo-0.10.tar.gz
 
-    # emerge -tv CPANPLUS
+Log in as root and unpack it in e.g. your home directory :
 
-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 :
+    # cd
+    # tar xzf /tmp/CPANPLUS-Dist-Gentoo-0.10.tar.gz
+    # cd CPANPLUS-Dist-Gentoo-0.10
 
-    # FEATURES="-protect-owned" emerge podlators
-    # FEATURES="-protect-owned" emerge ExtUtils-MakeMaker
+Bootstrap L<CPANPLUS::Dist::Gentoo> using the bundled shell script C<g-cpanp> :
 
-You may need to run each of these commands two times for them to succeed.
+    # PERL5LIB=blib/lib samples/g-cpanp CPANPLUS::Dist::Gentoo
 
-At this point, you can bootstrap L<CPANPLUS::Dist::Gentoo> using the system L<CPANPLUS> :
+Finally, emerge the C<CPANPLUS-Dist-Gentoo> ebuild you've just generated :
 
-    # PERL5LIB=/root/CPANPLUS-Dist-Gentoo-0.10/blib/lib samples/g-cpanp CPANPLUS::Dist::Gentoo
     # emerge -tv CPANPLUS-Dist-Gentoo
