Looks like MLD_LISTENER_QUERY ought to be defined in the system's icmp6.h header. Maybe not on older systems. Or maybe they forgot to include that header.

On my system /usr/include/netinet/icmp6.h has:

#define MLD6_LISTENER_QUERY		130 	/* multicast listener query */
#define MLD6_LISTENER_REPORT		131	/* multicast listener report */
#define MLD6_LISTENER_DONE		132	/* multicast listener done */

But no MLD_* versions.

If these were renamed in 10.6.8 release, then at least 10.4–10.5 will be in trouble just as like: hardly the issue is exclusive to specific builds of 10.6.

Apple wouldn't have made a breaking change in a stable OS. The rename probably happened prior to the 10.6.0 release, and you're running a 10.6 prerelease.

For compatibility with that and 10.5 and earlier, some subset of this is probably needed:

Maybe add these to legacy-support by the way?
