Hi,

The two full implementations of YAML in perl are YAML (i.e. YAML.pm)
and YAML::Syck.  Neither of them has significant other dependencies.

   YAML - build_requires: Test::Base: 0.49
               requires: perl 5.6.1

   YAML::Syck - build requires a C compiler
               requires: perl 5.003

http://search.cpan.org/src/INGY/YAML-0.58/META.yml
http://search.cpan.org/src/AUTRIJUS/YAML-Syck-0.38/META.yml

What is not "well packaged" about these two distributions?

Is the reason Module::Build can't depend on YAML because it depends on
perl 5.6.1
and Module::Build seeks to support (depend on only) perl 5.5.3?

Module::Build has the following dependencies.

requires:
  Cwd: 0
  Data::Dumper: 0
  ExtUtils::Install: 0
  ExtUtils::Manifest: 0
  ExtUtils::Mkbootstrap: 0
  File::Basename: 0
  File::Compare: 0
  File::Copy: 0
  File::Find: 0
  File::Path: 0
  File::Spec: 0.82
  Getopt::Long: 0
  IO::File: 0
  Test::Harness: 0
  Text::ParseWords: 0
  perl: 5.005_03
build_requires:
  Test::More: 0
recommends:
  Archive::Tar: 1.08
  ExtUtils::Install: 0.3
  Module::Signature: 0.21
  Pod::Readme: 0.04

http://search.cpan.org/src/KWILLIAMS/Module-Build-0.27_09/META.yml

The only reason to have *another* external YAML distribution is to
have one which
has even fewer dependencies (i.e. perl 5.005_03 aka 5.5.3, no C compiler).

Some possible names for the module...

   YAML::Simple
   YAML::Portable

If a YAML::Simple existed (which implemented a sufficient subset of
the YAML spec),
would this significantly improve the dependency characteristics of the
tool chain?
