Ran into bug 821427 while trying to emerge driftnet-1.3.0. Checked the developer web page and saw that 1.4.0 has been released and is not in portage. Renamed the existing ebuild in my local overlay to driftnet-1.4.0.ebuild and it compiles and installs successfully. Reproducible: Always
Created attachment 849185 [details] driftnet-1.4.0.ebuild
Thank you for the report. We do not need an ebuild in the attachment, if it is mostly a simple bump (/rename) next time.
