Clean up CPAN.pm's environment variable the same way we do for CPANPLUS. Add an
example program showing local::lib employed programmatically (confound).
Add the beginnings of a troubleshooting section (pattern).

         - Don't allow dangerous settings for CPAN.pm that affect where CPAN
           installs stuff, as this conflicts with what we're trying to do.

+=head1 TROUBLESHOOTING
+
+If you've configured local::lib to install CPAN modules somewhere in to your
+home directory, and at some point later you try to install a module with C<cpan
+-i Foo::Bar>, but it fails with an error like: C<Warning: You do not have
+permissions to install into /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux at
+/usr/lib64/perl5/5.8.8/Foo/Bar.pm> and buried within the install log is an
+error saying C<'INSTALL_BASE' is not a known MakeMaker parameter name>, then
+you've somehow lost your updated ExtUtils::MakeMaker module.
+
+To remedy this situation, rerun the bootstrapping procedure documented above.
+
+Then, run C<rm -r ~/.cpan/build/Foo-Bar*>
+
+Finally, re-run C<cpan -i Foo::Bar> and it should install without problems.
