I'm sorry to answer so late but I was away for a while. The problem
with this code is that you don't give prefix dir to initial #walk
invocation. Dir class has a notion of working directory - you can
retrieve it with #pwd. #walk method never changes that class variable,
i.e. it does not #chdir into directories. Instead it receives prefix
parameter which is a relative path to current working directory. I
used to start from current dir - so I didn't pass "." to
walk. Following two calls are effectively equivalent:
Dir.new(".").walk "." {|p| puts p}
Dir.new(".").walk {|p| puts p}

But if you don't start walking from current dir - you should always
pass relative prefix to #walk. It's a tradeoff of not changing working
directory.
  Dir.new(tip_root).walk(tip_root) {|p| puts p }

I hope this helps and I suggest you to try mswin32 port of ruby. As I
said in some previous post - it's way faster than cygwin .
