I can confirm the issue. The build-log is exactly the same.

Both kde-apps/libkface-16.04.3 kde-apps/libkface-16.08.3 definitely build fine against media-libs/opencv-3.1.0-r4, I just tested on a slightly outdated box. Not being up to date with opencv right now, what has changed in the recent revisions? New contrib tarball?
