I was able to boot from the raidz pool, and now I have working 7.1- 
STABLE install booting off raidz pool. Sweet!
The problem was that I had "export"ed the pool, and gptzfsboot was not  
able to find it. I had to boot from the LiveFS CD,
zpool import it, reboot and everything worked.

Now I can only wait for ZFS v13 to hit -STABLE :)

Thanks!
