Please remove the package games-misc/fortune-mod-martin-piskernig from Gentoo because upstream has also been removed some time ago. Reproducible: Always
"upstream has also been removed some time ago" isn't a good reason to remove it from portage. Is there any other reason to remove it?
Thank you for your answer! One non-technical reason is that the packages consists of quotes from my postings in Usenet, some of which I am not very proud of today (flamewars etc.). Upstream kindfully removed it for that reason some time ago. I can not force you to remove the package but it would be very kind if you removed it. I don't think it has much of a user base (it is German and many quotes can only be understood regionally). If people are really keen on seeing me write on Usenet they could also use google groups nowadays...
that's a good reason. it's gone. thanks for the bug report.
