I think the problem it's having in the first case is related to 'dist_author'. It looks like it can't determine the author of your distribution. Normally that information is extracted from the POD of your module(s). If that's right, then the following patch should fix it - could you try it?

Cool, I'll make sure that patch is part of the next bugfix release in the 0.26xx series (assuming there is one - 0.28xx might beat it to the punch). Show quoted text

It should be in an "AUTHOR" section, like so: =head1 AUTHOR Nadim Ibn Hamouda El Khemir, nadim@khemir.net Show quoted text

Yeah, for that distribution it's missing some other piece of information besides the author, but I'm not sure what. What piece of information looks like it's missing from the META.yml file? Show quoted text

This is a behavior we've fixed in 0.27_xx - it used to "freeze" the decision about whether to use YAML according to whether YAML was present when you *installed* Module::Build. Now it will sense whether YAML became present after Module::Build was installed. To fix it in your case, you can run the following command: config_data --module Module::Build --set_feature YAML_support=1 assuming you let the config_data script be installed when you installed Module::Build. If you didn't, you could just hand-edit the Module::Build::ConfigData file. -Ken
