It does, but there was a freebsd-boot partition on each of the ZFS 
disks.  512K, even, so more than large enough for the current version of 
gptzfsboot.

We might have been looking at different disks in that gpart output. 
Incidentally, while the boot partition is usually first, I'm fairly sure 
that it does not have to be first and can be in any position.
