I’ve been working still on my laptop to day and I have managed to get mod_ruby onto apache without apache crashing or failing to start. I had to download and compile my own MySQL install so that I could compile PHP with MySQL so I now have the latest Apache with the latest Ruby, PHP and MySQL. I have also installed HP Linux Image and Printing drivers onto my mac allowing me to use my old HP P1000 at 1200dpi. All that it left to do is to get rid of the 403 errors I get from ruby with apache.
Because somethings are just hard to find online
