Creating poudriere jail fails with libmd.so.6 not found

I tried to create a new jail in my CURRENT from March 1
This fails with:

# poudriere jail -c -j 150-CURRENT -m src=/usr/src

I investigated the problem and the old libmd.so.6 is used by some
binaries in /usr/obj/usr/src/amd64.amd64/tmp/legacy/usr/sbin/mtree
which the 'make buildworld' copied to this place from the underlying old
system:

# ldd /usr/obj/usr/src/amd64.amd64/tmp/legacy/usr/sbin/mtree | grep libmd.so.6
	libmd.so.6 => not found (0)
# ldd /usr/obj/usr/src/amd64.amd64/tmp/legacy/usr/sbin/sort | grep libmd.so.6
	libmd.so.6 => not found (0)
# ls -l /usr/obj/usr/src/amd64.amd64/tmp/legacy/usr/sbin/mtree /usr/obj/usr/src/amd64.amd64/tmp/legacy/usr/sbin/sort
-r-xr-xr-x  1 root wheel 65392 Aug  6  2023 /usr/obj/usr/src/amd64.amd64/tmp/legacy/usr/sbin/mtree
-r-xr-xr-x  1 root wheel 62544 Aug  6  2023 /usr/obj/usr/src/amd64.amd64/tmp/legacy/usr/sbin/sort

Aug 6, 2023 the 14-CURRENT was setup where I built the now 15-CURRENT on
March 2:

# uname -a
FreeBSD jet 15.0-CURRENT FreeBSD 15.0-CURRENT #0 main-n275738-7ee310c80ea7: Sun Mar  2 01:13:00 CET 2025     guru@jet:/usr/obj/usr/src/amd64.amd64/sys/GENERIC amd64

What would be the correct way to fix this? Re-run 'make buildworld'
again? Or copying the shared lib libmd.so.6 into place?
