To build installation kits for Perl on OpenVMS, grab the tarball
of the latest stable release from http://www.perl.org, unpack
it, rename the top-level directory to "source" and zip it up
with Info-Zip. For example:
% zip -r source.zip source
or (on VMS):
$ zip -r source.zip [.source...]*.*
Then place source.zip alongside build_perlkit.com and simply do:
$ submit build_perlkit
Some hours later you should have a kit targeting the platform you
ran it on.
