Note how in this example, the vendor-supplied directories are in the
/usr hierarchy, while the directories reserved for the end user are in
site-specific files that are stored elsewhere on your organization's
network. One way to do that would be something like

locincpth is a space-separated list of include directories to search.
Configure will automatically add the appropriate -I directives.

=head1 Coexistence with earlier versions of perl 5
-Perl 5.17 is not binary compatible with earlier versions of Perl.
+Perl 5.17.11 is not binary compatible with earlier versions of Perl.
In other words, you will have to recompile your XS modules.
In general, you can usually safely upgrade from one version of Perl (e.g.
libraries after 5.6.0, but not for executables. TODO?) One convenient
way to do this is by using a separate prefix for each version, such as
- sh Configure -Dprefix=/opt/perl5.17.4
+ sh Configure -Dprefix=/opt/perl5.17.11
-and adding /opt/perl5.17.4/bin to the shell PATH variable. Such users
+and adding /opt/perl5.17.11/bin to the shell PATH variable. Such users
may also wish to add a symbolic link /usr/local/bin/perl so that
scripts can still start with #!/usr/local/bin/perl.

yet.
