in reply to I am not a META.yml expert.....

I think that in the META.yml it is not allowed to use arbitrary YAML, but only a (sadly poorly defined, afaict) subset.

Maybe try to use Test::YAML::Meta to verify it locally.

    Thanks. I have tested with Test::YAML::Meta and Test::YAML::Valid and it confirms that there is a problem with my META.yml. However it does not pinpoint what the problem is, nor how it got generated incorrectly. Thus I am still stuck. Also curiously the problem seems to be identified by YAML::Syck but not straight YAML.

    Edit: Just to make this clear. If I run this code: 

    use strict;
use warnings;
use Test::More;

use Test::YAML::Valid qw(-Syck);
yaml_file_ok('META.yml', 'META.yml is YAML');

    it indicates that the YAML is invalid. If I remove the "-Syck" it's okay. If I run it on other META.yml it's okay. I find this very puzzling as it suggests not just that there is something mysteriously wrong with my YAML, but that Syck is not that transparent.

      Looks like a bug in ExtUtils::MakeMaker, it doesn't quote abstract properly.

        Yes I realized that the colon is the problem last night. I got quite worried about whether this was a problem with YAML::Syck and contacted Andreas Koenig. He pointed out I should have read the email the PAUSE daemon sent which does indeed contain that error message. It's now fixed.
