I hate to follow up my own post, but this panic appears to have damaged
my filesystem, because when I restart the install, I get this:

ipv6# make DESTDIR=/scratch/build install
(cd /usr/src/etc && make distrib-dirs)
install  -d -o root -g wheel -m 755 /scratch/build
mtree -def mtree/NetBSD.dist -p /scratch/build/ -u
cd /scratch/build; rm -f sys; ln -s usr/src/sys sys
panic: lfs_ialloc: inuse inode 8601 on the free list
Stopped in ln at        cpu_Debugger+0x4:       leave
db> reboot                                           
syncing disks...
