 Hi!

 {{{
 $ cat foo.cc
 int main()
 {
   return 0;
 }
 $ clang++-mp-devel foo.cc
 $ ./a.out
 $ clang++-mp-devel foo.cc -fsanitize=address
 $ ./a.out
 dyld: Library not loaded: /opt/local/libexec/llvm-

   Reason: image not found
 zsh: abort      ./a.out
 }}}

 I don't remember when asan worked properly in MacPorts, I think I've
 always had to add symlinks to work around this.  Unfortunately, only one
 compiler can be fixed at a time this way.

 Cheers!
