I've been looking at the test package for the upcoming 5.18.2 release
announced in http://cygwin.com/ml/cygwin-announce/2014-04/msg00038.html
and I'd like to contest that assertion again.

TL;DR: I still propose to keep each Perl distribution as a separate
package (yes, I'm willing to ITP them) and move perl_vendor to an
umbrella package that simply bundles those individual packages plus
perhaps a README.


Long version:

First off, there is a flurry of changes in the content of perl_vendor
that you didn't list in the announcement.  This is exactly my gripe with
opaque bundling: anyone who's been relying on perl_vendor to deliver a
certain set of Perl distributions will suddenly find that some have been
removed and others have been added and the only way to find that out is
to look into the source archive.  This also means you're going to have a
package conflict if any of those distributions are packaged (either
locally or in cygports) or some of your intended changes become hidden
behind things in site_perl (which may or may not be the latest version
or missing some of the patches you applied to vendor_perl).

Secondly, some of the distributions you've removed from perl_vendor are
actually run-time requirements of the modules that are in (plus a few
new ones that weren't in the old perl_vendor).  Packaging errors on the
Perl side are a possibility (although usually these are missing
dependencies, not additional ones), but barring that there's 25 more
distributions that need to be delivered with perl_vendor:

--8<---------------cut here---------------start------------->8---
            perl-Sub-Install
          perl-Data-OptList
          perl-Encode-Locale
          perl-HTTP-Date
          perl-IO-HTML
          perl-LWP-MediaTypes
        perl-HTTP-Message
        perl-Sub-Exporter
      perl-Data-Dump
      perl-File-Listing
      perl-HTTP-Cookies
      perl-HTTP-Daemon

  perl-Data-Section
  perl-Devel-Autoflush
  perl-Digest-HMAC
  perl-Mozilla-CA
  perl-Text-Template
  perl-YAML-Syck
--8<---------------cut here---------------end--------------->8---

Then there's 19 more distributions needed for building (those do not
need to be in perl_vendor), bringing the total for a successful build
from scratch to 125 distributions:

If you build and install these in this order, then you can bootstrap
perl_vendor without using CPAN or cpanminus in about an hour or two.
The dependency walker that produces the above output also produces the
necessary cygport files, which only seldomly need some manual edits
(mainly for setting test options).  At the moment I just build from the
command line, but putting this into a Makefile is certainly possible.
