It still needs to know where to find the import file to get D 
information like names and types out of it that aren't in the lib 
(well they sorta are but not exactly, in any case it isn't 
implemented to try it now).

So either still pass it mod.d there, which makes the library 
useless, or pass `-Isomething` where there's a `pack/mod.d` or 
`pack/mod.di` file with the function prototypes. dmd -H can make 
mod.di out of mod.d for you in some cases automatically.
