I have now updated to NetBSD 9_Stable (with ipf support due to
unresolved issues with npf nat under 8_Stable as per:
http://mail-index.netbsd.org/tech-net/2021/01/01/msg008000.html )

And still no joy compiling MesaLib under latest pkgsource/HEAD 2021.1.16
NetBSD 9_Stable, amd64
MesaLib: MesaLib-20.0.6nb1
