Until the p6c system is fixed here's a short term fix that will at least let zef install modules from cpan.
zef --help This lists a config file mine is : CONFIGURATION /home/sproctor/.config/zef/config.json Open that file and fine the "p6c" section. Set enabled to 0 and zef will stop trying to access the ecosystem modules. It's not perfect as not everything is in CPAN but it should help. -- Simon Proctor Cognoscite aliquid novum cotidie http://www.khanate.co.uk/
