It takes ages to get opencv-4 (#663730). Could meanwhile opencv-3.4.x be updated ?
We currently have 3.4.1 in tree (released in feb. 2018 ! ref: https://opencv.org/opencv-3-4-1/).
The current version as of today is 3.4.8

Masking follow-up as "~" and downgrading as of today:
. . . [ebuild UD ] media-libs/opencv-2.4.13-r3 [3.4.1-r5]
should not be the preferred solution.
An ebuild was pushed on portage for opencv-4 (~amd64), but it has a lot of problems (doesn't emerge, pkgconfig missing, headers broken).
Could you meanwhile bumps opencv 3.4.x ???
