Noticed that when $DEBUG=true, any FileUtils.mv call produces two  
(rescued) exceptions:

$ ls  
sim-1.0.0.zip  
$ irb

/usr/lib/ruby/1.8/fileutils.rb:

```
  def fu_same?(a, b) #:nodoc:
    if fu_have_st_ino?
      st1 = File.stat(a)

```

1420: st2 = File.stat(b)

```
  def lstat
    if dereference?

```

1200: @lstat ||= File.stat(path())  
else  
@lstat ||= File.lstat(path())  
end  
end
