Um, pardon the stupid question, but did you just forgot to link 
it? I can't see a mention of it anywhere in both the old json and 
dub.sdl, and I don't see subpackages either. (does it links 
implicitly by the compiler?)

Also if it's digged up somewhere, another possibility is the link 
order issue(you need to put libs in order that adds linker 
symbols for previous libs to consume, for circular dependencies 
you can specify libs multiple times). The MS linker and LLVM 
linkers(not sure about GNU gold) does some work for you so you 
don't have to reorder libs most of the time.
