Did you try this solution?  It doesn't work:

+ # ifconfig tun0 freebie 139.130.136.129 netmask 255.255.255.255 alias
+ ifconfig: ioctl (SIOCAIFADDR): File exists

In fact, it works anyway:

+ # ifconfig tun0
+ tun0: flags=8151<UP,POINTOPOINT,RUNNING,PROMISC,MULTICAST> mtu 1500
+         inet 139.130.136.133 --> 139.130.136.129 netmask 0xffffffff 
+         inet 192.109.197.137 --> 139.130.136.129 netmask 0xffffffff 

I think this is a bug.
