digitalmars.D.learn - App Build Error

I'm having an issue with building my app - even a simple trivial 
app (shown below).

I receive the following error message:

	cc -arch i386 -framework CoreFoundation -lobjc -liconv: No such 
file or directory
	--- errorlevel 255
	
I've removed and reinstalled DMD - same issue.  I'm not really 
sure whats going on.

OS X version?
Have you configured your dmd.conf? iirc it requires linker path 
changes or something.
Have you looked in /usr/local/lib for libiconv.* ?
Have you any idea why it's targeting i386 and not, say i686 and 
not passing -m64 by default?
(You're getting the arch mismatch because you passed -m64 and dmd 
for some reason didn't)

I'm running OSX 10.10.5.  I've not changed dmd.conf.  I did a 
fresh install (2.068) after removing the previous version 
(2.067).  I noticed the arch mismatch, but this is how it was 
installed.  Nothing special.

Thanks!  Ben.
