[DRE-maint] Bug#593082: libxml-parser-ruby1.9.1: load error with ruby 1.9.2

[Laurent Arnoud]

File « digest.rb » seem missing since 0.7.0:
http://www.yoshidam.net/xmlparser-0.7.0.tar.gz

But present on http://www.yoshidam.net/xmlparser-0.6.8.tar.gz

The changelog for 0.7.0 (http://www.yoshidam.net/Ruby.html#xmlparser) say:
Changes of version 0.7.0
 * suppot Ruby 1.9.1.
 * remove some experimental libraries. <- (Maybe a missing cleaning ?)
 * remove all example programs.
