I just saw in other post that Alon suggested TKLPatching an instalation of Ruby Enterprise. I just took the first part of my Gitorious TKLPatch and converted it to a TKLPatch that can be used as base for installing other Ruby projects. This patch is for turnkey-core-beta-lucid-x86.

Hope it's usefull! 

Features:

* Ruby Enterprise 1.8.7 

* RubyGems 1.3.7

* Passenger 2.2.15

* SSL Support Enabled.

* Apache Rewrite module enabled (convenience)

What it Does:

1. Download and installs Ruby Enterprise & RubyGems 1.3.7. Creates symlinks to usr/bin

# Install Ruby Enterprise and RubyGems
wget http://rubyforge.org/frs/download.php/71100/ruby-enterprise_1.8.7-2010.02_i386_ubuntu10.04.deb
dpkg -i ruby-enterprise_1.8.7-2010.02_i386_ubuntu10.04.deb
rm ruby-enterprise_1.8.7-2010.02_i386_ubuntu10.04.deb
ln -s /usr/local/bin/ruby /usr/bin/ruby
wget http://production.cf.rubygems.org/rubygems/rubygems-1.3.7.tgz
tar xf rubygems-1.3.7.tgz
cd rubygems-1.3.7/
ruby setup.rb
ln -s /usr/local/bin/gem /usr/bin/gem
cd /root/
rm -Rf rubygems-1.3.7/

2. Installs apache, passenger and apache modules

install build-essential apache2-mpm-prefork apache2-prefork-dev libapr1-dev libaprutil1-dev ssl-cert
gem install --no-ri --no-rdoc --version 2.2.15 passenger
/usr/local/lib/ruby/gems/1.8/gems/passenger-2.2.15/bin/passenger-install-apache2-module -a
echo "LoadModule passenger_module /usr/local/lib/ruby/gems/1.8/gems/passenger-2.2.15/ext/apache2/mod_passenger.so" > /etc/apache2/mods-available/passenger.load
echo "<IfModule mod_passenger.c>" > /etc/apache2/mods-available/passenger.conf
echo "   PassengerRoot /usr/local/lib/ruby/gems/1.8/gems/passenger-2.2.15" >> /etc/apache2/mods-available/passenger.conf
echo "   PassengerRuby /usr/local/bin/ruby" >> /etc/apache2/mods-available/passenger.conf
echo "</IfModule>" >> /etc/apache2/mods-available/passenger.conf
a2enmod passenger
a2enmod rewrite  
a2enmod ssl 
a2ensite default-ssl
service apache2 restart
