Comment (by isolated-matrix):

 I have just checked my `/usr/local/lib` directory and found several
 `libatomic` files. I've no idea where they came from or what program they
 belong to, so I'm afraid to delete them... But I moved them into a
 quarantine folder, tried running the installation again and it completed.

 Not sure why macports is searching for this library if it doesn't need it.
 So maybe the solution would be to tell macports not to look for it.
