Here's the failure when building p5.16-redis:

*** WARNING WARNING WARNING WARNING WARNING WARNING WARNING WARNING ***

If you're seeing this warning, your toolchain is really, really old* and you'll
almost certainly have problems installing CPAN modules from this century. But
never fear, dear user, for we have the technology to fix this!

If you're using CPAN.pm to install things, then you can upgrade it using:

    cpan CPAN

If you're using CPANPLUS to install things, then you can upgrade it using:

    cpanp CPANPLUS

If you're using cpanminus, you shouldn't be seeing this message in the first
place, so please file an issue on github.

If you're installing manually, please retrain your fingers to run Build.PL
when present instead.

This public service announcement was brought to you by the Perl Toolchain
Gang, the irc.perl.org #toolchain IRC channel, and the number 42.

----

* Alternatively, you are doing something overly clever, in which case you
should consider setting the 'prefer_installer' config option in CPAN.pm, or
'prefer_makefile' in CPANPLUS, to 'mb" and '0' respectively.

You can also silence this warning for future installations by setting the
PERL_MM_FALLBACK_SILENCE_WARNING environment variable.

I didn't try to analyse the error yet, but it's not necessarily the redis' fault.

Given the change in r129966: is there any way to figure this out automatically with cpan2port? Why does one need port:p${perl5.major}-module-build-tiny? Isn't that automatic? If not: should it be?

[dbevans (David B. Evans)]

This error is symptomatic of the need to use perl5.use_module_build with p5-module-build-tiny instead of p5-module-build.

Clues are:

• presence of Build.PL
• Build.PL uses Module::Build::Tiny (line 2)

Fixed in r129966.

[mojca (Mojca Miklavec)]

Thank you. Are you willing to open a ticket to make an improvement in cpan2port to respect that?

[dbevans (David B. Evans)]

I have to confess that I don't use cpan2port because it's not fool proof and so if I have to look in META.json/META.yml to check for dependency errors, I might just as well do that in the first place.

I'll try to add a ticket when I have time (probably after Christmas). I want to look in cpan2port to see how it works first.
