AFAICT nobody is using Ruby DBI anymore. I originally packaged it as a dependency of Samizdat and Graffiti, which have been converted to Sequel since Dec 2011. No other packages in Debian depend on ruby-dbi or ruby-dbd-*, lets remove them.
Same story with ruby-mysql. It has been superceded by ruby-mysql2, and only 2 packages in Debian still depend on it: ruby-graffiti and ruby-opennebula. Both use it via Sequel, which also supports ruby-mysql2, meaning that both packages are likely to only need a dependency fix in debian/control. Thoughts, objections? -- Dmitry Borodaenko
