I don’t know whether Ruby 1.9 is broken or not. What I’m sure of, is that with your proposed dependency scheme, you will not be able to ensure dependencies will be installed for Ruby 1.9. Which means changing the Ruby version with alternatives would just break user systems. If users want Ruby 1.9, serve them Ruby 1.9 and get rid of the applications not supporting it (or use explicit versions for them). But don’t serve them a system that is half-compatible with Ruby 1.9 and not up to the stability expectations of a Debian system. If you choose to support several Ruby interpreters through alternatives, you have to specify the interface that /usr/bin/ruby provides, just like for Java. This means settling on the lowest common denominator of what these interpreters can provide - and this is *completely opposite* to the users’ request, since they want to benefit from the improvements in Ruby 1.9. > Anyway.

There are thousands of such half-assed “documents”, and we receive many bug reports of users breaking their systems after that. A few days ago, a user complained that his gnome-panel was broken.
