Ubuntu Dapper will only install ruby as high as 1.8.4 which is not ideal sometimes. To upgrade an existing ruby installation to 1.8.6 do the following.

  sudo apt-get install build-essential
sudo apt-get install libreadline5 libreadline5-dev
wget ftp://ftp.ruby-lang.org/pub/ruby/1.8/ruby-1.8.6.tar.gz
tar -xzf ruby-1.8.6.tar.gz
cd ruby-1.8.6
./configure --prefix=/usr/local --enable-pthread --with-readline-dir=/usr/local
make
sudo make install

Even if you had rubygems you need to install it and all your gems! Again.

   wget http://rubyforge.org/frs/download.php/35283/rubygems-1.1.1.tgz
tar -xzf rubygems-1.1.1.tgz
cd rubygems-1.1.1
sudo ruby setup.rb

Now this is where you need to do a little fix. Openssl will not work out of the box and some application need it so you should just set it up now.

Note: If apt-get libssl-dev complains about a not found run: sudo apt-get update

  sudo apt-get install libopenssl-ruby
sudo apt-get install libssl-dev
 
cd ~/src/ruby-1.8.6/ext/openssl
ruby extconf.rb
make
sudo make install

And thats it!
