The stf interface does not have POINTOPOINT set, (nor should it).
  So, dhclient wants to try and manage it.

  We discussed awhile ago adding some kind of flag to interfaces that 
can never be configured via DHCP (e.g. stf) so that dhclient could ignore
them. 
  As an alternative measure some way to do:

  "dhclient -w wi0 ep0"

  and not have have dhclient exit if neither interface has been
found. (Because, for instance, I'm in my room, or on the plane)
