in reply to AI::NNEasy to setup fast a Neural Network using just Perl and XS.

Just a minor nit: I tried installing AI::NNEasy via CPAN, and it complained about "Class::HPLOO" not being found. Could you put it in as a dependency, so that CPAN will download and install Class::HPLOO first (if not installed) ?

    Actually this is a bug of CPAN.pm, since it's already there: 
    use Class::HPLOO::MakeMaker ;

WriteMakefile(
    'NAME'          => 'AI::NNEasy' ,
    'VERSION_FROM'  => 'lib/AI/NNEasy.pm' ,
    'PREREQ_PM'     => {
      'Class::HPLOO'  => 0.21 ,
      'Inline'        => 0.44 ,
    } ,
    ($] >= 5.005 ?
      ( ABSTRACT_FROM => 'lib/AI/NNEasy.pm',
        AUTHOR        => 'Graciliano M. P. <gmpassos@cpan.org>'
       ) : ()
     ),
);

      How do you expect CPAN.pm to get past: 

      use Class::HPLOO::MakeMa­ker ;

      [download]

      to be able to run the code that tells it that it needs Class::HPLOO ?

      I looked, and CPAN.pm parses the Makefile so you should try including a pre-built Makefile in your distribution (that will get replaced). I also checked CPANPLUS.pm and it also parses Makefiles to find prerequisites.

      I don't know if including a Makefile will be enough to fix this problem, but you shouldn't just blithely blame the circular dependencies you've created with Class::HPLOO on "a bug in CPAN.pm".

      Please uninstall your copy of Class::HPLOO, download your module(s) that use it from CPAN, and test that they install correctly.

        Wow! Big mistake!

        I have just added the new MakeMa­ker in the last release based in what Inline does. This was added to install the compiled XS in the Perl distribution.

        I will look for a solution using the default MakeMa­ker.

        But note that the prerequisite bug at CPAN really exists and is a common bug that reports a lot of wrong tests by the CPAN testers.
