Well, Reini's chimed in after he'd seen my patch and I just added that
functionality on top of what was already implemented and in use by
myself. I guess I can change my cygport generator instead to use
CPAN_DIR when needed, but haven't got around doing so.

Autodetection just doesn't work, with both false positives and negatives
in spades. Your proposed change probably produces more false negatives
with not much change in the false positive rate. So why bother?
There are actually multiple modules on CPAN attempting that sort of
thing, one slower than the other and still none of them gets it right in
all cases. So your chances of doing better with a shell script are
pretty much zero. All Perl distributions come with metadata that tell
you the dependencies among them already, so I just need a way to
transfer that exactly into the cygport file (which again gets generated
from that exact metadata, not written by hand). By way of example,
Cygwin has several packages that support Perl OO layers, of which there
are many (Moose, Mouse, Moo, Mo…) so a dependency check pulling in all
of them would end up creating a dependency chain that's at least 200
more distributions. Note that I very deliberately do not package Moose,
which is huge.

Then there ought to be. :-)

I obviously like my patch better, because it keeps that line in the
output no matter what the tag is (plus colors it so it's easier to catch
a left over wrong tag when scrolling through the backlog).

That's a vestigial of some other patch that was ordered before this one
before I created the branch, I think.

When looking in setup.log.full… this output used to go to the console,
but got axed quite some time ago.

Sure, but that's not cygport's business, no?
