Yes you are :)

This is what I use to use an up to date dcraw successfully with digikam.

But this needs to rework the dcraw-8.69-backward-compat patch each time 
dcraw is updated to maintain the interface so that digikam can handle it 
correctly.

And while digikam is not updated, you cannot benefits from the new dcraw 
noise filter within digikam for example since it's not manage in the 
current digikam interface.

Yes, using an external program with moving interface is really nasty :)
I have a dream, where Dave Coffin would build his program like a library 
with a stable interface ;)

Guillaume
