The issue I have here is that Main doesn't need to be compiled 
with the versions defined by its dependents.

So if someone defines a version list in their dub.sdl then all 
those versions need to be defined in my dub.sdl when in reality I 
don't care and just want to link to the library with those 
versions defined.
