Created attachment 353894 [details] emerge --info attached, though, likely irrelevant https://metacpan.org/changes/release/LEONT/Module-Build-0.4007 ( Gentoo 0.400.700 ) >=0.4004 ( Gentoo 0.400.400 ) dependencies are to be expected due to the addition of test_requires support. I've had 0.4005 ( Gentoo 0.400.500 ) in the perl-experimental overlay for a while now due to upstream ( aka: me ) requesting recent versions. But any more recent perl-core/Module-Build in tree, even hardmasked, would be welcome =)
Made a 0.400.700 Module-Build https://github.com/kentfredric/proxy-maint/compare/yngwin:f44ccd154e176feb8607da9f6bf51790ec2f7997...Module-Build Changelogs, metadata.xml ( some CPAN id's are going away ) I'm not proxy maint for MB, I just needed this for something I'd be maintaining and its thus a convenient place. Tested, works for me.
Done.
