Yubico is long longer maintaining ykneo-ccid-tools and suggests to switch to libykneomgr (has same + additional functionality) https://github.com/Yubico/ykneo-ccid-tools old project with unmaintained msg. https://github.com/Yubico/libykneomgr new project I'll post some ebuild later today unless someone gets to it before me.
Created attachment 372832 [details] libykneomgr-0.0.2.ebuild FYI, here is an ebuild I just put together. Also posted here: https://github.com/marineam/misc-overlay/blob/36eca0f1023f733d13ae58f7537092c670b29a17/sys-auth/libykneomgr/libykneomgr-0.0.2.ebuild
sys-auth/libykneomgr has been added to Portage. This bug can be closed.
