The UFRaw README explicitly states:
Do not package the executables generated by by --enable-extras. These extras
are there for testing the code during development. They are of no interest
to end user. Specifically, if you want to package dcraw, you should use
Dave's original code and not UFRaw's modified code.

Despite this reminder, the UFRaw "own" /usr/bin/dcraw file has been included in
the Leap 42.1 package, which generates the conflict with the dcraw package.

This conflict also caused an issue with the upgrade from 13.2 0.19.2 UFRaw
version which resulted in this Leap 42.1 system having to use the 13.2 version:
any attempt to upgrade UFRaw would have resulted in the removal of the Leap
42.1 dcraw package.
(The 13.2 livexiv2-13 (orphan; 13.2 only) package also has to remain on this
system.)
