This is another "CPAN utils" post (sort of) but this time around resolving and fetching tarballs 😃
cpan -g
First let's start by using the venerable CPAN:
$ cpan -g Parser::MGC

sourcepan
Then look at the more developer oriented sourcepan:
$ sourcepan Acme::LSD

sourcepan --git could even init for you a repository...
cpan-get
Continue with the newborn cpan-get:
$ cpan-get Test::More
'http://cpan.metacpan.org/authors/id/E/EX/EXODIST/Test-Simple-1.302183.tar.gz' was downloaded.
MetaCPAN::Client + HTTP::Simple
And finish by a mixed MetaCPAN API client + an HTTP client (with no error handling at all 💀):
# Init MetaCPAN client
use MetaCPAN::Client;
my $mcpan = MetaCPAN::Client->new();
# Resolve url
my $download_url = $mcpan->download_url('ExtUtils::MakeMaker');
# Download
use HTTP::Simple;
getstore($download_url->{data}->{download_url}, "EUMM.tgz");
(Should be possible fetch with MetaCPAN::Client, if you know how, please comment)
