The recommended method for installing a rails 2.3.x application is to use "bundler" to manage the gem files.  This will lead to a clean work environment that will not conflict with any other rails applications.  First start by reading the documentation about changes that you'll need to make to use bundler with Rails 2.3.x

An example of using bundler with PHP Shell:

$ mkdir rails23
$ cd rails23
$ bundle init
Writing new Gemfile to /infra/lamp/mounts/emc256/emc256test2/rails/rails23/Gemfile
$ editor Gemfile
$ cat Gemfile
# A sample Gemfile
source "http://rubygems.org"
gem "rails","2.3.11"
$ bundle install --path vendor
Fetching source index for http://rubygems.org/
Installing rake (0.9.2)
Installing activesupport (2.3.11)
Installing rack (1.1.2)
Installing actionpack (2.3.11)
Installing actionmailer (2.3.11)
Installing activerecord (2.3.11)
Installing activeresource (2.3.11)
Installing rails (2.3.11)
Using bundler (1.0.18)

Gemfile.lock  Rakefile	config/  doc/  log/  script/  tmp/
# modify per bundler directions
$ editor config/boot.rb
# create new file per bundler directions
$ editor config/preinitializer.rb

After you have modified your rails 2.3.x application to use bundler you'll need to create a symlink from your virtualhost root directory to your rails application.  The following is an example for the virtual host "test-vhostssl.hosting.cornell.edu" :

 $ pwd
/infra/lamp/mounts/emc256/emc256test2/htdocs/test-vhostssl.hosting.cornell.edu
# find relative path to rails application
$ ls ../../rails
rails23/  rails30/  rails31/
# create symlink to "public" directory
$ ln -s ../../rails/rails23/public rails23
cd rails23
# create .htaccess file for passenger
$ cat .htaccess
RackBaseURI /rails23
PassengerAppRoot /infra/lamp/mounts/emc256/emc256test2/rails/rails23/
