Installing Ruby 1.9.1 on Ubuntu 9.04

The dependencies are simple;
sudo apt-get install build-essential libssl-dev libreadline5 libreadline5-dev zlib1g zlib1g-dev

Then the usual process…

mkdir ~/src && cd ~/src
wget ftp://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.1-p0.tar.gz
tar -xvf ruby-1.9.1-p0.tar.gz
cd ruby-1.9.1-p0
./configure
make
make test
sudo make install
