I use a similar setup (the second connection goes actually through the first 
one). The problem is that vpnc binds its UDP port to 0.0.0.0, meaning any 
network device. So the second instance cannot bind to the same port again.

To avoid this, I patched vpnc some time ago and added a --bindaddr 
<address-to-bind-to> option, but AFAIR it was not included in the release. 
But you might still find it in the list archives.

Of course, you then have to take care of the routes yourself, AFAIK the 
vpnc-connect scripts are not designed for two concurrent connections (hence 
the pid-file conflict).
