wrong base_uri and package_file on debian 

Seems like the url path to the  debian package has changed also the package name:
On basho riak's  cookbook chef try to grab the package for debian 6 (64) from: 
  http://s3.amazonaws.com/downloads.basho.com/riak/1.2/1.2.1/debian/squeeze/riak-1.2.1-1_amd64.deb

and u get 403 "Forbidden", 

Looking at http://basho.com/resources/downloads/   the debian package url seems to be: 
http://s3.amazonaws.com/downloads.basho.com/riak/1.2/1.2.1/debian/6/riak_1.2.1-1_amd64.deb

tweaking the base_uri and package file  for debian platform fix this.
