you need to tell the compiler where to look to find pyd (which it 
can't find in '/Library/D/dmd/src/phobos' or 
'/Library/D/dmd/src/druntime/import').
If you are invoking the compiler yourself use the `-I` switch 
(`-Ipath/to/pyd`).
Or if you are using dub (I recommend this) make sure that is is 
in your list of dependencies.
