Greetings, my latest update 'emerge -q -uDN @world' failed at glib-2.60.6. Continuing with --skipfirst succeeded. Today, after a new 'emerge --sync', 'emerge -q -uDN @system' still failed with the same error.
My Gentoo is mostly stable. The relevant info can be found at http://www.triffids.de/pub/gentoo/glib-2.60.6/ What to do? If more info is needed I will upload it to the above location. Hartmut
