Best way to upgrade from 1.8.2 to 1.8.4 on Linux?


I have installed from source Ruby in the folder /usr/lib/ruby-1.8.2/.
(I use Linux)
If I do “which ruby” I get /usr/local/bin/ruby. It seems that Ruby has
created the folder /usr/local/bin and filled it with ruby, irb, etc…
I don’t mind, this is all fine.

Now my question is: when at XMAS Metz dressed like Santa will bring me
Ruby 1.8.4, how should I upgrade?

I was thinking do to the following:

  1. Remove the folder /usr/lib/ruuby-1.8.2/
  2. Install Ruby 1.8.4 from source in /usr/lib/ruby-1.8.4/
  3. During the Installation of Ruby 1.8.4, it will overwrite
    automatically the folder /usr/local/bin/ with the new versions of ruby,
    irb, etc… I am not sure if it works automatically in this way. Can
    you confirm?
    If it doesn’t happen out-of-the-box, I was thinking to create a
    symbolic link from /usr/local/bin to /usr/lib/ruby-1.8.4/bin/.

Regarding Gem and Rails, I will probably just remove Gem’s folder and
reinstall it. And then just reinstall the main gems that I am using
including Rails. The rails websites/application that I have done are
saved elsewhere and shouldn’t be affected.

Is it a good approach? How will you do it?
