I wonder about installing the latest version of Ruby on Ubuntu 9.04. Now I can run through the ./configure and make stuff fine, but what I wonder about: how to avoid conflicts with the packaging system? For example if some other package I install depends on Ruby, wouldn't the package manager install the (outdated) Ruby package and in the worst case overwrite my files?
So I think I need some way to tell Ubuntu that Ruby is in fact already installed?

Use `gem install -v` You may already be familiar with gem install , but if you add the -v flag, you can specify the version of the gem to install. Using -v you can specify an exact version or use version comparators.
Run the command rvm install 2.7. 1 . Alternatively, you can run rvm install ruby which will install the latest stable version (this will install v2. 7.0).
Save yourself the headache and use RVM (Ruby Version Manager)
Keep in mind, Rails 3 works best with Ruby 1.9.2. Ruby 1.9.2 fixes up quite a few bugs in 1.9.1 and is preferable to running 1.9.1.
With RVM installing 1.9.2 is a breeze.

sudo apt-get install ruby1.9.1-full (http://www.ruby-lang.org/en/downloads/)
