This error is created by Build.PL when any prerequisite raised an error. Ideally, there would be a list of additional error messages at the bottom of the output:

my %errors = map {
    eval "require $_; $_->VERSION($configure_requires{$_}); 1";
    $_ => $@,
} keys %configure_requires;

if (!grep $_, values %errors)
{
    # This section for Pod-Coverage-Moose was generated by Dist::Zilla
+::Plugin::ModuleBuildTiny 0.017.
    use strict;
    use warnings;


    use 5.006;
    # use Module::Build::Tiny 0.034;
    Module::Build::Tiny::Build_PL();

}
else
{
    if (not $ENV{PERL_MB_FALLBACK_SILENCE_WARNING})
    {
        warn <<'EOW'
*** WARNING WARNING WARNING WARNING WARNING WARNING WARNING WARNING **
+*

...
You can also silence this warning for future installations by setting 
+the
PERL_MB_FALLBACK_SILENCE_WARNING environment variable, but please don'
+t do
that until you fix your toolchain as described above.

The weird thing is that the section starting with

Errors from configure prereqs:
[download]

... is missing, as are the actual error messages. So I guess that what we are seeing is not the whole truth or that Data::Dumper output went to STDOUT and that is not shown.
