Usually `dub.selections.json` should not be committed for libraries, 
only for applications.

With the latest version of Dub it's now possible to specify which 
compiler is required [1]. That could potentially have solved your 
problem. I'm not sure if this means that Dub will try to pick an older 
version of the dependency if the compiler requirement doesn't match.
