Do you have options IPSEC in your kernel?  I believe this may prevent
vpnc from sending/receiving the encapsulated packets.  If you're not
using IPSEC for anything else, removing the option should do the trick.

Also, make sure that you're running it as root, not only for raw socket
access but also so it can create the tun device.

I use vpnc quite a bit on CURRENT, and it works quite well, with the
exception of fighting with dhclient over the resolv.conf file.  (I
know about exit hooks, but then I forget to remove them and wonder why
DNS isn't working).
