Hi,

You can apply this patch against dcraw 8.69 that make it works with 
digikam 0.9.1 by maintaining the interface just like 8.41 (and 
backporting bilateral noise filter feature used by digikam dialog) :
http://gentoo.xwing.info/media-gfx/dcraw/files/dcraw-8.69-backward-
compat.patch

Then :
- either integrate the patched version of dcraw in digikam 0.9.1 as you 
did ;
- or use this patch http://gentoo.xwing.info/media-gfx/digikam/files/
digikam-0.9.1-external-dcraw.patch against digikam 0.9.1 to use external 
backported dcraw (I personally prefer this solution, even if it force me 
to maintain myself backward compatibility of dcraw to work with the 
current digikam version)

Other solution of course is as Gilles said to use svn version that 
integrate a more recent version of dcraw

Chears,
Guillaume
