problem building gstreamer1-plugins-gl

Hello:
	I recently updated a system to:

FreeBSD 14.0-CURRENT #0 main-f0a15aafcb
Mon Oct 31 08:19:54 EDT 2022
amd64

	and am rebuilding ports.
	Pursuant to ports/UPDATING, I deleted everything gstreamer1 and
started over; many things build fine, but gstreamer1-plugins-gl fails
to build, reporting: 

Dependency (anonymous) from subproject subprojects/gl-headers found: YES 2019.1.0
Run-time dependency opengl found: YES 4.5

	The full log is available on rewuest.
	<insert "kicked in the head by a mule" look>
	What did I do wrong?  More importantly - how do I fix it?
