If I link in phobos manually most of the errors go away, I'm left 
with"

rt_init(void)" (?rt_init@@YAHXZ) referenced in function main

This mainly seems that the d code is not being linked with the c 
code.

But I guess this is all on VisualD's end since since it seems 
just to be the command line not getting the correct stuff, for 
some oddball reasons.
