There also seems to be a netlink header discrepancy on Dapper. netlink.h 
contains the following #defines:

#define NETLINK_ROUTE           0       /* Routing/device 
hook                          */
#define NETLINK_SKIP            1       /* Reserved for 
ENskip                          */
#define NETLINK_USERSOCK        2       /* Reserved for user mode socket 
protocols      */
#define NETLINK_FIREWALL        3       /* Firewalling 
hook                             */
#define NETLINK_TCPDIAG         4       /* TCP socket 
monitoring                        */
#define NETLINK_NFLOG           5       /* netfilter/iptables ULOG */
#define NETLINK_XFRM            6       /* ipsec */
#define NETLINK_SELINUX         7       /* SELinux event notifications */
#define NETLINK_ARPD            8
#define NETLINK_AUDIT           9       /* auditing */
#define NETLINK_ROUTE6          11      /* af_inet6 route comm channel */
#define NETLINK_IP6_FW          13
#define NETLINK_DNRTMSG         14      /* DECnet routing messages */
#define NETLINK_KOBJECT_UEVENT  15      /* Kernel messages to userspace */
#define NETLINK_TAPBASE         16      /* 16 to 31 are ethertap */

while Feisty has:

#define NETLINK_ROUTE           0       /* Routing/device 
hook                          */
#define NETLINK_UNUSED          1       /* Unused 
number                                */
#define NETLINK_USERSOCK        2       /* Reserved for user mode socket 
protocols      */
#define NETLINK_FIREWALL        3       /* Firewalling 
hook                             */
#define NETLINK_INET_DIAG       4       /* INET socket 
monitoring                       */
#define NETLINK_NFLOG           5       /* netfilter/iptables ULOG */
#define NETLINK_XFRM            6       /* ipsec */
#define NETLINK_SELINUX         7       /* SELinux event notifications */
#define NETLINK_ISCSI           8       /* Open-iSCSI */
#define NETLINK_AUDIT           9       /* auditing */
#define NETLINK_FIB_LOOKUP      10
#define NETLINK_CONNECTOR       11
#define NETLINK_NETFILTER       12      /* netfilter subsystem */
#define NETLINK_IP6_FW          13
#define NETLINK_DNRTMSG         14      /* DECnet routing messages */
#define NETLINK_KOBJECT_UEVENT  15      /* Kernel messages to userspace */
#define NETLINK_GENERIC         16

Notice that NETLINK_CONNECTOR, which god uses, is not defined in the 
former. Adding it to netlink.h on Dapper allows the extension to 
compile, but doesn't make the event conditions work. We'll look into 
this some more and see if we can come up with a good solution for Dapper.
