The issue here is that the CMSG_LEN and CMSG_SPACE macros are not defined in /usr/include/sys/socket.h on all systems.  However, all the functions/macros that these CMSG_LEN and CMSG_SPACE are defined.  Thus, my solution to the problem was to conditionally define these two macros in gsocket.c.  Probably not a good long term solution, but it works...
