In reply to Leon Katsnelson.

Good question, Leon. Generally speaking, I went with what people are still using the most. The 1.9.2 version of this tutorial only require you to install the ruby1.9.1-full package instead of ruby-full, and then skip the Rubygems installation (it’s included in 1.9). However, here is where it gets ugly…

The package name is 1.9.1 and so are all the executables: ruby1.9.1, gem1.9.1, ri1.9.1, and so on… but the actual version is Ruby 1.9.2. Furthermore, the built-in Rubygems is an old 1.3.7 version, and you are not really supposed to upgrade the Ubuntu package via gem update –system. In short, those interested in running Ruby 1.9.2 would probably be best served by a multiple installation manager like RVM or simply the good old compilation from source.

Antonio, great tutorial. One question? Why did you choose Ruby 1.8.7 and not 1.9.2?
