ping hanging.

As for 4400::34 It is not a darpa net IP, but the host ip is valid on this 
host. In this case the libexec directory had been deleted, possibly by me, 
possibly not. re `make install`ing the plugs seems to have worked.

I too need this caffeine level indicator. I hope it will support HTCPCP.

I am not now attemtping to determine if the ping lock problem persists. 
(this problem was also noticed with IPv4 hosts, ampr and darpa, both 
routed and RFC1918.)
