Same idea as the Groovy and Grails posting, most of the steps are the same but here they are. Download JRuby from http://www.jruby.org/, as of writing this the latest release is 1.6.0. I’m downloading the tar file, I believe it the same as the zip file just different format used to compress the files. $ cd Downloads $ tar -xzf jruby-bin-1.6.0.tar.gz Now lets move it to our /usr/share folder and make the needed symbolic link.
