This thread of timely. However I am running 10.8.5 Mountain Lion.

I ran into the same compiler error tonight after switching my LDC
compile from gcc-4.8 to system clang with -stdlib=libc++ so it will use
libc++ instead of libstdc++.

I think the error is that template in logger.h uses operator<< for
ostream& which is not defined when instantiated.

This worked for me,

--- a/gen/logger.h
+++ b/gen/logger.h
@@ -15,7 +15,8 @@
 #ifndef LDC_GEN_LOGGER_H
 #define LDC_GEN_LOGGER_H
 
-#include <iosfwd>
+//#include <iosfwd>
+#include <ostream>
 
 namespace llvm {
     class Type;

I'll bet libstdc++ headers pulled in more classes and avoided the error.

Now I it looks like I have to build libconfig++ against libc++ too
(macport libconfig-hr uses libstdc++). I am getting an ldc2 link error.
Oh well.
