This is due to the fact that the zpool version scheme has changed. They are now using feature flags to indicate versions, and thus the output of zpool upgrade -v has changed.
Old output (actually taken from a Solaris 10u10 box):
davis@plinian ~ $ sudo zpool upgrade -v
Password:
This system is currently running ZFS pool version 22.
The following versions are supported:
VER DESCRIPTION
--- --------------------------------------------------------
1 Initial ZFS version
2 Ditto blocks (replicated metadata)
3 Hot spares and double parity RAID-Z
4 zpool history
5 Compression using the gzip algorithm
6 bootfs pool property
7 Separate intent log devices
8 Delegated administration
9 refquota and refreservation properties
10 Cache devices
11 Improved scrub performance
12 Snapshot properties
13 snapused property
14 passthrough-x aclinherit
15 user/group space accounting
16 stmf property support
17 Triple-parity RAID-Z
18 Snapshot user holds
19 Log device removal
20 Compression using zle (zero-length encoding)
21 Reserved
22 Received properties
For more information on a particular version, including supported releases,
see the ZFS Administration Guide.
New output looks like this - no explicit "This system is currently running ZFS pool version blah":
davis@anfnfsl ~ $ sudo zpool upgrade -v
This system supports ZFS pool feature flags.

I guess there are two possible courses of action here:
Since the official Oracle zfs versions apparently go higher than 28 now and don't support feature flags, I think the first option is the better one. We should probably add another fact for zfs_feature_flags.
I'm not sure if this is due to the recent bump to zfsonlinux 0.6.0-rc14 (from rc8) or not, but the zpool_version fact fails now at run time.
