I get this:

$ make port-lib-depends-check

mpv-0.37.0(multimedia/mpv):
Extra:  SPIRV-Tools-shared.0 Xinerama.6

Looks like upstream explicitly stopped using Xinerama so that one can be
removed.

What's up with SPIRV-Tools-shared and the new LIB_DEPENDS on
spirv-tools - I see that the port still uses -Dspirv-cross=disabled,
I could have missed something but that does seem to disable anything
to do with spirv?
