From what I see, you need a stepped ferule to fit the stop built into the derailleur, but there's a netter way. Lead the housing under the BB, and up between the chainstays (forward of the KS plate). Let the housing end about halfway to the FD,m and route the wire straight to the pinch bolt.
The only drawback to this is that the open end faces up and will trap water and dirt if you ride in wet or dirty conditions. This is easily remedied with a boot like the one used on V-brakes.
BTW - this method, doesn't depend on the clip, and you can simply bypass it (I assume it's still needed for the RD), running the bear wire under the BB shell, using a short piece of teflon tubing or tape to lower friction.
