The ebuild for winesetupk is still in the online package database, but emerge can't find it. Reproducible: Always Steps to Reproduce: 1. 2. 3.
`ls /usr/portage/app-emulation/winesetuptk/` if that doesnt work then try running `emerge sync` again
I just double checked, and in fact moved -r3 to stable. winesetuptk is definitely in the portage tree.
Works now after another sync.
