Change AIX update process to exclude updating Perl and or just it's external modules

Currently when an Admin goes to upgrade AIX (ie. TL/SP levels),
the upgrade process also will update perl runtime along with man pages. This process will at times overlay/"backlevel" modules which have manually been added to the perl (from CPAN) in order to support some function, (ie. Spreadsheet xlsx). Thus the perl program using this "once installed" modules will abort. The Admin will then have to track down, and re-install the module. THis is very time consuming,tedious, and troubleshooting to identify the "backleveled" module is extremely difficult. WHen in a production environment, this is un-acceptable.

    It's not a good idea for a user to replace files installed as part of an
    installp package (whether perl.rte or any package at all). This can make
    it appear to the system that there is a corruption in the fileset, and it
    may have unintended consequences if some other utility is specifically
    dependent on the original version of the file, if there is a possible
    compatibility change. Also there is the issue cited here: an update to
    that fileset for maintenance will overwrite a modified file with the
    original copy.

    It is more appropriate to put one's own copies of alternate versions of files
    into another path, and point to those versions where needed. For perl, one
    way to do this is to have a local directory with different desired versions
    of modules, and point the PERL5LIB environment variable to the top of this path.

    Another option with AIX is to install the latest version of Perl from the
    "AIX Toolbox" website, which gives the user access to a newer version of Perl
    than is provided on the AIX operating system media. This version installs
    into a different path, so users can choose between the fixed stable version
    provided with the OS or the newer optional updated version provided with the

    No special provisions are planned for perl.rte with respect to system updates.
