Ruby on Rails and ISPConfig3 on Squeeze

[aldo]

I would like to use Ruby on Rails in some site managed with ISPConfig3 (on Debian 6 Squeeze).

I found these Howtos:
http://www.howtoforge.com/getting-st...-ruby-on-rails
http://www.howtoforge.com/ruby_on_rails_debian_etch

The first one is a "getting started" that does not refer to ISPConfig.
The second one, that is very close to my needs, involves the installation of MySQL, which I have already installed, and it is a little dated, so I'm afraid of messing up my installation.

So I am looking for info/docs on installing Ruby 1.9.3 and Ruby on Rails on a site managed by ISPConfig3.

Any help will be appreciated.
