dmd -v doesn't outputs the absolute path of the dmd binary.
Information about the path that must be used in dmd.conf
needs some deduction from the dmd -v output (when the dmd.conf is 
working).

But when there is a wrong dmd.conf (with wrong paths inside) picked up by 
dmd, then there is no information at all:

dmd main.d -v
parse     main
importall main
import    object        (object.d)
object.d: Error: module object cannot read file 'object.d'

Having the absolute path to dmd and dmd.conf would help a lot at this 
point.
I've seen countless people struggling and also failing with this problem..
