So, I figured it out! I used the wrong example for mydll.def.

---------------------------------------------
LIBRARY         MYDLL
DESCRIPTION     'My DLL written in D'

EXETYPE		NT
CODE            PRELOAD DISCARDABLE
DATA            WRITE

EXPORTS
		DllGetClassObject       @2
		DllCanUnloadNow         @3
		DllRegisterServer       @4
		DllUnregisterServer     @5
----------------------------------------------
The above will cause errors: even though it makes you think that 
it should be mydll.def it is not.

----------------------------------------------
LIBRARY "mydll.dll"
EXETYPE NT
SUBSYSTEM WINDOWS
CODE SHARED EXECUTE
DATA WRITE
----------------------------------------------
The above is the correct .def contents

Thanks all!
