Ruby 1.9.2 and Rails 3.0.3 are now considered stable by what appears to be everyone but the packagers. apt installs Ruby using a non-standard configuration too, when you do `apt-get install ruby1.8`, the executable is `ruby1.8`. Nobody in their right minds these days would install it with the `1.8` suffix. Ruby version management is best taken care of with RVM, as that's better built for it than a general package manager such as apt.
