Install Ruby 1.8.6 On CentOS 5.X Using A Yum Repository
The latest available Ruby version in the default CentOS repositories is currently Ruby version 1.8.5. Many packages in the default CentOS repos are notorious for lagging way behind what versions of the packages are currently available. Even though Ruby 1.8.7 and Ruby 1.9.X are available I simply needed to get Ruby 1.8.6 installed for a project I was working on so I used the information below to install Ruby 1.8.6 on CentOS Linux using the Yum Package Manager.
