I actually read the headers this time:

*/usr/include/netinet6/in6.h*:
/* RFC 3542 define the following socket options in a manner incompatible
 * with RFC 2292:
 *   IPV6_PKTINFO
 *   IPV6_HOPLIMIT
 *   IPV6_NEXTHOP
 *   IPV6_HOPOPTS
 *   IPV6_DSTOPTS
 *   IPV6_RTHDR
 *
 * To use the new IPv6 Sockets options introduced by RFC 3542
 * the constant __APPLE_USE_RFC_3542 must be defined before
 * including <netinet/in.h>
 *
 * To use the old IPv6 Sockets options from RFC 2292
 * the constant __APPLE_USE_RFC_2292 must be defined before
 * including <netinet/in.h>
 *
 * Note that eventually RFC 3542 is going to be the
 * default and RFC 2292 will be obsolete.
 */

The RFC 2292 version of IPV6_PKTINFO:

#define IPV6_2292PKTINFO        19 /* bool; send/recv if, src/dst addr */

The RFC 3542 version:

#define IPV6_RECVPKTINFO        61 /* bool; recv if, dst addr
                                    * APPLE: Value purposely different than
FreeBSD (36) to avoid
                                    * collision with definition of
IPV6_TCLASS in previous
                                    * darwin implementations */
