It works on MacOS X - and possibly on BSD - when I change the
line above to:

  $ cp -al r3 r4 2>/dev/null || (cd r3 && find . -print | cpio -dplm ../r4 2>/dev/null; cd ..)

I have to redirect stderr to /dev/null for cpio because it
complains that it has not selected (all) the files; perhaps
someone with cpio experience knows about an option to avoid this.
