After an update to json-c-0.11 i have a lot of problems. No sound (can't load alsa-lib), gnome does not start and i can't build a lot of programs. Because of this, i can't do a downgrade to json-c-0.10-r1.

Please post your `emerge --info' output in a comment. Also, please describe the various problems in more detail. GNOME writes logs with useful error messages and it isn't obvious at all what "loading alsa-lib" means. Also, why can't you downgrade? If you need technical support, please use our forums, IRC chat, or mailing lists instead of this bug tracker.
