In the end I did the reduction by hand and discovered that the 
problem is that the behaviour of dub changed. It seems to now 
exclude the mainSourceFile of other configurations in the build 
(which I guess shouldn't matter) except we had an old 
configuration which after some renaming had a wrong 
mainSourceFile which was needed for the build of the 
configuration in question.

Thanks for the suggestions.
