Hi Ned,
The difference is that for mirrored pools, zpool list displays the
actual available space so that if you have a mirrored pool of two
30-GB disks, zpool list will display 30 GBs, which should jibe with
the zfs list output of available space for file systems.
For RAIDZ pools, zpool list displays the RAW pool space and zfs list
displays actual available pool space for file systems.
The inconsistency in the way zpool list displays AVAIL pool space for
RAIDZ and mirrored pools has been around for awhile.

Why doesn't the space that is reported by the zpool list command and the
zfs list command match?

"zpool list" output show raw disk usage, including all redundant copies of
metadata, all redundant copies of data blocks, all redundancy accounted for
(mirror, raidz), etc.
Perhaps that's true after a certain version? It's not true in the latest
solaris 10. Here are my results on a fully patched solaris 10 installation,
installed from the latest disc (10u9):
