I haven't tried LDC yet, though I've heard good things about it. Maybe I
should check it out sometime.

Did you define main() in prog.d (or somewhere)? The second line of the
output here seems to indicate that you didn't. I think the latest git
dmd is patched so that a more helpful error message is provided in this
case, but this unhelpful screenful of errors is what the current release
dmd gives when main() isn't defined.
