Tom, Solaris 10u3 will deliver both the original libzfs.so.1 and a new libzfs.so.2, which will include the new interface to zpool_iter. One way to determine which version of the library you are using is to look for libzfs_init(). This function only appears in the new library.
Also worth noting that once we deliver this change in s10u3 there will only be one libzfs.h so if you continue to use the old library you will need to maintain a private copy of the old libzfs.h.
