A typical way to install local::lib is using what is known as the
"bootstrapping" technique. You would do this if your system administrator
hasn't already installed local::lib. In this case, you'll need to install
-local::lib in your home directory.

+you will still want to set up your environment variables, as discussed in
+step 4 (and for Windows users, see L</Differences when using this module under Win32>).
1. Download and unpack the local::lib tarball from CPAN (search for "Download"
on the CPAN page about local::lib). Do this as an ordinary user, not as root

=head1 CREATING A SELF-CONTAINED SET OF MODULES
-You can use local::lib to prepare a directory which contains a module and all
-of its non-core dependencies. The C<--self-contained> option ignores any
-globally installed modules when resolving dependencies, only considering
-modules installed in a "local::lib" directory or provided by core Perl.
-
-A use-case for this feature would be to prepare to deploy a whole "stack" of
-module dependencies on a new machine, even if you have copies of the same
-dependencies installed globally already.
-
-The C<--self-contained> option should be used like this:
-
- # Install LWP and *all non-core* dependencies to the 'my_lwp' directory
- perl -MCPAN -Mlocal::lib=--self-contained,my_lwp -e 'CPAN::install(LWP)'
-
-Note that some dependencies may involve C-based "XS" code even if your target
-module doesn't. The issue of dealing with XS vs Pure Perl code is beyond the scope
-of what local::lib provides.
+See L<lib::core::only|lib::core::only> for one way to do this - but note that
+there are a number of caveats, and the best approach is always to perform a
+build against a clean perl (i.e. site and vendor as close to empty as possible).
