Since you have to respin for the Makefile issue - could you rewrite this
to use 2001:db8 for all addresses? ULA is a funny and odd thing.
LOCAL_V6 = "2001:db8:1::1"
REMOTE_V6 = "2001:db8:1::2"
LOCAL_PREFIX_V6 = "2001:db8:2::0/64"
?

dunno if the fallback is really necessary, not including the prefix
length is a bit of a bug IMO.
