Here's the fix. It has to do with El Capitan and brew.

I found the fix:

$ sudo brew update
$ sudo brew uninstall --force dmd
$ sudo su
$ cd /Library
$ rm -rfd D
$ exit
$ sudo brew install dmd

This not only takes one from an older dmd to a more current version (in my
case, from 2.068 to 2.069), but it also fixes a bug where /Library/D doesn't
get updated. (Besides, the El Capitan version of 2.069 now doesn't use
/Library/D.)

When I did that, I found I was able to compile like so:

volomike:cpptod4 mike$ dmd -m64 -L-framework -LFoundation test.d
volomike:cpptod4 mike$ ls
testtest.dtest.o
volomike:cpptod4 mike$ ./test
2015-12-15 03:07:52.669 test[7308:116958] Hello World!
volomike:cpptod4 mike$

So, it not only used an Objective C NSString object, but it fed it to NSLog and
I got console output in NSLog format.

I added the code below for reference. It works perfectly fine for me using
Yosemite. It's most likely an issue with the installation of the compiler.

// test.d
module main;

extern (Objective-C)
interface Class
{
NSString alloc() @selector("alloc");
}

extern (Objective-C)
interface NSString
{
NSString initWithUTF8String(in char* str) @selector("initWithUTF8String:");
void release() @selector("release");
}

extern (C) void NSLog(NSString, ...);
extern (C) Class objc_lookUpClass(in char* name);

void main()
{
auto cls = objc_lookUpClass("NSString");
auto str = cls.alloc().initWithUTF8String("Hello World!");
NSLog(str);
str.release();
}

Changing from FIXED to WORKSFORME since this was apparently an installation
problem.
