Title: update to require digest/md5 instead of md5

s3sync didn't work for me giving error of:
`
home/sroot/.rvm/rubies/ruby-1.9.3-p327/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in require': cannot load such file -- md5 (LoadError)
`

It appears ruby 1.9 uses digest/md5 instead of md5
I suggest someone more knowledgeable checks this before accepting the pull request.
