Internal error: failed to initialize ZFS library

[Scott]

Installed MacZFS 74.3.3 to Power Mac G5 running OS X 10.5. Trying to create pool on second drive formatted to GUID with a  /dev/disk0s2 partition. I keep getting above error even though I am entering zpool command ( zpool create name /dev/disk0s2 ) at root prompt in bash. I cannot find answer to resolve.

Thanks.
