Looks like that package needs the GLESv3 headers, I had only installed
the GLESv2 ones. Not worked out how to handle more than one target
include directory in the Makefiles yet.

I wanted GLESv2 to be able to build kmscube, one of the Panfrost
developers had suggested it as a simpler test app than just starting X
and seeing what happened. It isn't in pkgsrc so I had not made the
changes to pkgtools/x11-links.

The x11/zutty package builds for me now but complains about the 'C'
locale when I run it and doesn't display text correctly.

I will clean up the Makefile a bit first.

I had tried adding more debug to this a while ago but didn't find
anything obviously wrong.
