If this issue is just that Mac OS allows hard links for directories then 
  simply changing link() to symlink() for directories: 
http://perldoc.perl.org/functions/symlink.html should fix the issue, 
shouldn't it?

Something like:

if(-d $object) {
   symlink(...)
} else {
   link(...)
}

Yours,
Roland
