For some reason gtk30 stops with
root at www:/usr/ports/x11-toolkits/gtk30 # gdkkeys-wayland.c:34:10: fatal error: 'fribidi.h' file not found
#include <fribidi.h>

I tried compiling gtk20 in the hopes it might provide the missing file,
but it completed successfully and fribidi.h remains absent. 

Last resort was to remake wayland, but that didn't help, gtk30 still
stops with missing fribidi.h

Is there a way out of this box?
