In hier(7), it says that "/usr/local" is for "executables, libraries, 
etc. not included by the basic operating system", so I guess DMD fits 
this quite well.

I'm preparing an installer for D for Xcode and made it install DMD at 
/usr/local/dmd and /usr/local/dmd2, with symlinks at /usr/local/bin/dmd 
(system-prefered version) /usr/local/bin/dmd1 (1.x) and 
/usr/local/bin/dmd2 (2.x). This makes it easy to choose the version you 
want within Xcode.

For some reasons, the symlinks works fine with Xcode. But they aren't 
working from the command line (dmd complains that it can't find 
object.o). I've made a small C program to replace the symlink:

	#include <unistd.h>

	int main(unsigned int argc, char **argv) {
		argv[0] = "/usr/local/dmd/osx/bin/dmd";
		execv("/usr/local/dmd/osx/bin/dmd", argv);
	}

No more problem from the command line.
