8.47: How do I keep my own module/library directory?

    When you build modules, tell Perl where to install the modules.

    For "Makefile.PL"-based distributions, use the INSTALL_BASE option when
    generating Makefiles:

            perl Makefile.PL INSTALL_BASE=/mydir/perl

    You can set this in your CPAN.pm configuration so modules automatically
    install in your private library directory when you use the CPAN.pm

            % cpan
            cpan> o conf makepl_arg INSTALL_BASE=/mydir/perl
            cpan> o conf commit

    For "Build.PL"-based distributions, use the --install_base option:

            perl Build.PL --install_base /mydir/perl

    You can configure CPAN.pm to automatically use this option too:

            % cpan
            cpan> o conf mbuild_arg --install_base /mydir/perl
            cpan> o conf commit

    INSTALL_BASE tells these tools to put your modules into
    /mydir/perl/lib/perl5. See "How do I add a directory to my include path
    (@INC) at runtime?" for details on how to run your newly installed

    There is one caveat with INSTALL_BASE, though, since it acts differently
    than the PREFIX and LIB settings that older versions of
    ExtUtils::MakeMaker advocated. INSTALL_BASE does not support installing
    modules for multiple versions of Perl or different architectures under
    the same directory. You should consider if you really want that , and if
    you do, use the older PREFIX and LIB settings. See the
    ExtUtils::Makemaker documentation for more details.
