I'm trying to install RedMine (www.redmine.org) which is an awesome project management tool. I have access to a CentOS machine which is supposed to host it. I found some guide specifying how to install an old version of ruby and I tried to install it and then update to no avail. The latest version of rails requires a newer version of ruby than what I've got installed.
Could someone point me in the direction of how I can upgrade that ruby version? Yum hasn't registered it so I'm kind of stuck..
