A CentOS Ruby Interest group
Firstly, CentOS is super popular out there with the ruby guys and there are quite a few ruby based apps deployed on CentOS these days.
Secondly, every man - his dog - and kitchen sink seem to be building ruby rpms. Not apps or gems or anything, but Ruby itself. There must be over a dozen repos and over a few hundred private rpm builds floating around.
What needs to happen for these people to merge efforts ? CentOS is more than capable of hosting out-of-distro builds, either in Extras or CentOSPlus and there is plenty of precedence in the ecosystem to use namespace overloading to handle multiple build variants. Its not pretty, but it works. And using a sensible set of defaults also means that its mostly new-user friendly.
I think with Ruby (on Rails) more than with anything else (i.e. php, perl) there is a big gap between sysadmins caring for the stability of their machines and web developers screaming the latest and greatest.
If you just look around the net for ruby192 packaging, you will see how many people are attempting it. Once the basic stuff is in place, we can expand to look at complete framework stacks like RoR etc. I think starting at the base is the way to get this off the ground.
As an example, the ruby187 backport from CentOS-6 to CentOS-5 at http://centos.karan.org/el5/ruby187/ has had many thousand downloads in the last few weeks
I'm use for CentOS Endpoint repos (https://packages.endpoint.com/) for installing RubyEE version, but in this time their repo is outdated (actual version is 1.8.7-2011.03, but in EP repos - 1.8.7-2010.01, maybe this abadoned?)
Would be nice to have an actual rubyEE repo for CentOS5.x :)
