 Replying to [comment:2 ryandesign]:
 > Is this still a problem with opencv @3.3.1?

 Me, I cannot tell. I do not know how to upgrade and neither does `port`
 know. (Just ran a `selfupdate`.)

 What I *can* tell is that `ffmpeg-devel  @20171210_0` is unusable as well.
 Recent `opencv @3.2.0_1+avx2+eigen+tbb` builds with `ffmpeg-devel
 @20171018_0+gpl2+gpl3+nonfree+x11`.
