Can't rebuild kernel with ZFS v15

Thank you for responding.

For two reasons I know it's running zfs v14 after the rebuild:

1)  During boot, a message shows:

ZFS Filesystem version 4
ZFS Storage pool version 14

2)  After getting to the failed root mount point of the boot (after it  
fails to mount my zfs root), I enter:


to get to my boot partition (which must remain UFS obviously, hehe), and  
try to mount my pools with the 'zfsmount' command, however it errors with  
something similar to:

"storage pool version does not match"

I can only get my system working again by manually moving /boot/kernel to  
/boot/kernel.bad (or whatever) and replacing it with the previous kernel.
