I'll check that.

The setup for ruby seems a little messed up in the Ubuntu repositories 
(i guess its also the same for Debian). Almost all packages are only 
referenced for 1.9.1. e.g.

$ apt-cache search ruby1.9
...
ruby1.9.1 - Interpreter of object-oriented scripting language Ruby
ruby1.9.1-dev - Header files for compiling extension modules for the 
Ruby 1.9.1
ruby1.9.1-full - Ruby 1.9.1 full installation
ruby1.9.3 - Interpreter of object-oriented scripting language Ruby, 
version 1.9.3

No clear naming conventions (ruby1.8, ruby-1.9.1, ...)

Even using $ ruby1.9.1 -v   you get the version description for 1.9.3.
