Subject: | Module::Build::Base does "require YAML" only then uses YAML::Node |
More recent YAMLs no longer automatically load YAML::Node; Module::Build
should be doing a 'use' or 'require' for any YAML package it directly
references in order to ensure it continues to work in future. Currently,
upgrading YAML to 0.53 or 54 breaks M::B's ability to write META.yml and
hence to build dists.
