This is an auto-filled bug because app-shells/shish fails to compile. The issue was originally discovered on amd64, but it may be reproducible on other arches as well. If you think that a different summary clarifies the issue better, feel free to change it. Attached build log and emerge --info. NOTE: Since this is an auto-filled bug, while the log says to include other logs in the report, is not always possibile to do it automatically. So, if other logs are needed please ask them..
