works for me :

   Ara@JEN ~
   $ cat a.rb
     require 'alib'

     def dir_size dir
       size = 0
       totalled = {}
       ALib::Util::find2(dir, 'follow' => true) do |path, stat|
         begin
           next if totalled[stat.ino]
           next unless stat.file?
           size += stat.size
         ensure
           totalled[stat.ino] = true
         end
       end
       size
     end

     p dir_size('.')

   Ara@JEN ~
   $ ruby a.rb
   29432845

   Ara@JEN ~
   $ du -sb .
   29432903        .

   Ara@JEN ~
   $ ruby -r rbconfig -r yaml -e'y Config::CONFIG' |egrep -i win
   target: i686-pc-cygwin
   ac_ct_WINDRES: windres
   WINDRES: windres
   archdir: /usr/lib/ruby/1.8/i386-cygwin
   sitearch: i386-cygwin
   arch: i386-cygwin
   host_os: cygwin
   build: i686-pc-cygwin
   host: i686-pc-cygwin
   build_os: cygwin
   target_os: cygwin
   sitearchdir: /usr/lib/ruby/site_ruby/1.8/i386-cygwin

so it seems like your ruby may be broken - how'd you install it?

cheers.
