in reply to perlbrew clone-modules fails to install lots of modules

> Despite your assertion to the contrary, in many cases your "unclonable" modules are missing prerequisites.

Thank you monks! I see what you guys mean about the prerequisites by checking a bunch of the build.log files. Sorry for doubting you. Things like App::perlfind and Astro::Catalog and Astro::SpaceTrack require LWP::Protocol::https and did finally install once I forced Net::SSLeay. There are a couple of others that had these problems:

  • Acme::Tools - forced install 
    #   Failed test at t/02_general.t line 188.
#          got: 'server-3-163-125-2.lax54.r.cloudfront.net'
#     expected: 'www.vg.no'

#   Failed test at t/02_general.t line 189.

      URI::ws - removed from CPAN? unknown

      That is still on CPAN but note that it is part of the URI dist.

        URI::ws ended up on my list because I used list-modules and diff to find out which modules were missing to make my list that was posted here. Something is not right with perlbrew (I guess it's perlbrew but who knows)! Check this out: 
        % perlbrew use perl-5.38.2                    
% perlbrew list-modules | grep 'URI'
URI
URI::Find
URI::Find::Delimited
URI::ws

% perlbrew use perl-5.42.0                    
% perlbrew list-modules | grep 'URI'
URI
URI::Find
URI::Find::Delimited

      There is still Color::Rgb on CPAN (note the spelling).

        When I noticed modules were missing from doing 

        perlbrew clone-modules perl-5.38.2 perl-5.42.0
        I put the results of list-modules for both versions into respective text files and ran diff. Perlbrew listed the Color::Rgb in 5.38 as Color::RGB which caused clone-modules to fail for that module. I just tried to install Color::RGB manually on 5.42 and it failed of course. So I installed Color::Rgb into 5.42 and ran list-modules again and sure enough perlbrew reports that module as Color::RGB! When I went to CPAN and saw 
        Color::Rgb - Simple rgb.txt parsing class
Color::RGB::Util - Utilities related to RGB colors
        I didn't know what to think, maybe it got renamed? But I checked out the changes and it did not so I don't know what is going on with perlbrew. Try it yourself: 
        % cpanm -v Color::Rgb
% perlbrew list-modules | grep -i 'color::rgb'
Color::RGB

          I revisited the github issue and decided to take a look at what ExtUtils::Installed has to say about Color::Rgb: 
          % perl -MExtUtils::Installed -le '@_=ExtUtils::Installed->new->modules;@_=grep/color::rgb/i,@_;print for@_'
Color::RGB
Color::RGB::Util
          What about the packlist? 
          % perl -MExtUtils::Installed -le 'print ExtUtils::Installed->new->packlist("Color::RGB")->packlist_file'
/perl5/perlbrew/perls/perl-5.42.0/lib/site_perl/5.42.0/darwin-2level/auto/Color/RGB/.packlist
          Inside the packlist? 
          % cat /perl5/perlbrew/perls/perl-5.42.0/lib/site_perl/5.42.0/darwin-2level/auto/Color/RGB/.packlist
/perl5/perlbrew/perls/perl-5.42.0/lib/site_perl/5.42.0/Color/Rgb.pm
/perl5/perlbrew/perls/perl-5.42.0/man/man3/Color::Rgb.3
          The source of this issue still eludes me but I don't think perlbrew is the problem anymore. The output of Module::Metadata shows nothing unusual, module is reported as Color::Rgb.
