No line numbers in compiler error messages

[John Nixon via Digitalmars-d-learn]

I am using dmd v2.067.0 on Mac OSX with Terminal and I found the 
lack of line numbers surprising.
Is there something simple I am doing wrong? Do any of the 
switches on the command line do this?

BTW I only found out about D a couple of weeks back. It seems to 
be very impressive!
