[Openswan Users] Openswan ipv6 tunnels

I install the latest version of the 2.5 branch, 2.5.17 and tried again bringing up ipv6 tunnels.
I got the following error messages:
"can not load config '/etc/ipsec.conf': /etc/ipsec.conf:27: syntax error, unexpected STRING [connaddrfamily]"
When I comment out the line "connaddrfamily=ipv6" I get "non-ipv6 address may not contain `:'" in /var/log/messages
I tried using whack also to add a IPv6 tunnel using the command
"ipsec whack --name tunipv6 --ipv6 --tunnelipv6 --host 2000:7:6:5:4:3:2:1 --to --host 6400:7:6:5:4:3:2:2 --psk --encrypt --pfs --ikelifetime 600 --ipseclifetime 300 --rekeymargin 20"
When i try bring up the tunnel using "ipsec auto --up tunipv6" I get the same ike messages being received on the second Openswan Gateway, but no replies. This is also the behaviour I get when using 2.4.9

Is there any parameters I'm missing when using whack?
