poudriere jail buildworld fails: ld-elf.so.1: Shared object "libutil.so.9" not found

I'm trying build a poudriere jail so I can build (arm) pfsense packages. 
The base system is amd64 (15.1-RELEASE-p2) so QEMU is involved. This 
worked for years but not recently.

My toolchain notes are here:

     https://xse.com/leres/pfsense/toolchain.html

The newest jail I've been able to build is for pfsense 26.03.1 with 
FreeBSD /usr/src hash c215eef34550

(Is it just that my build system is too far behind 4bdcff554368 to be 
able to build it?)
