You are right. Back when I managed the _vendor list LWP was still
pre-6.0 and had different deps. I needed LWP to get CPAN and then
CPAN::TestReporter to work (at least bootstrap), so people can manage
their own packages, and do not rely on cygwin packages.
And the upstream maintainers get windows reports about failures, which
they need to fix their stuff. They always complain not getting any
windows reports, so they rather bitch. At least they get cygwin
reports for some time now.
I've updated the list of missing deps yesterday.

Sorry for the missing deps conflicts. This will be fixed in 5.14.2-3.

I do not agree. XS modules are not looked up from 5.10, and there is
no problem to continue using old modules if they were never updated on
If so, you well get new ones anyway with your next cpan or cpanm update.
It's a one-liner, but needs a lot of time to re-install everything from scratch.
$ cat ~/bin/cpanautoinstall
use CPAN; CPAN::Shell->install(CPAN::Shell->r)
$ perl -MCPAN -e'CPAN::Shell->install(CPAN::Shell->r)'
One other remaining problem is libtool's inability to mix static Win32CORE.a
with shared, so I'll probably add Win32CORE.o to libperl instead. It's a shame.
But perl is also blame as it still does not support installing
static_ext .a libs.
I have to do that manually.

Well, I'm not so happy with threads. They seem to be more broken than with 5.10.
But I like 5.14.2 generally at most of all also, much better than the
completely flawed 5.16.
