I've exchanged emails with Ken Williams and he has approved the switch. Later today, I will move the ExtUtils-CBuilder directory from cpan/ to dist/ (unless someone beats me to it) and will make any necessary modifications to ensure it can be released from that directory when needed after a blead maint release. I will update documentation and the current upstream repo to note the change. Porters with patches they've sent upstream or think need to be applied should feel free to apply them within blead instead. Regards, David
