Paul, where did you get the YAML-LibYAML-0.71 release? I can see it on rurban's
gihub fork and CPAN author's listing, but the CPAN search
<http://search.cpan.org/dist/YAML-LibYAML/> does not index it. Is that an
authorized release?

It showed up on MetaCPAN last week and I appear to have misread the authorized
information. Looks like I'll need to bump epoch and revert to 0.63.

As a workaraund I removed the three tests that fails in build:

https://koji.fedoraproject.org/koji/taskinfo?taskID=15632436

If I use YAML-LibYAML-0.71 on Fedora 24 then I can reproduce the error there.

In the meantime there is YAML-LibYAML-0.73 from rurban. It causes the same
errors in the Pegex tests.

--- Comment #5 from Reini Urban <rurban(a)cpan.org&gt; ---
Please see https://github.com/rurban/yaml-libyaml-pm/issues/1 which answers
your questions.

My CPAN uploads are entirely unauthorized. Please remove them from Fedora.

But they should be.
The Pegex tests are broken, due to the broken interpretation of the YAML specs,
which caused the problems with the various perl YAML libraries over the years.
See the links.
So in the end Pegex and YAML have to change it's tests to liberate it's
whitespace rules, amongst other bugs and inconsistencies.

But this will need a while. I started fixing it in March 2016, and got no
feedback so far. Only the cperl toolchain is fixed, but this is a perl5 fork
nobody is distributing. And the upstream maintainers are silent.

It seems that there is no problem any more. A scratch build on f26 completed
successful, so I will close this ticket.

--- Comment #8 from Paul Howarth <paul(a)city-fan.org&gt; ---
As there doesn't seem to be any prospect of a new authorized release of
YAML-LibYAML any time soon, I've now reverted to 0.63 in F-26 (though it will
have to wait for the end of the alpha freeze to appear) and Rawhide.
