We talked it over with the ruby sig and decided that rails 3.x was probably best for EPEL6. However, since then, I have run into several packages, including ones I use everyday that require rails 2.3.x or it's dependencies. I am proposing to put in rails 2.3.x and then have a rails3 package set when rails 3 is packaged in Fedora and ready to go. Currently, it looks like that might hit for F15, but then will probably take some additional work to get it ready for EPEL.
On a side note, rubygems.org now has as many package as CPAN does for perl. We could really use a lot more ruby packagers.
Also, if you are packaging something for Fedora and don't wish to maintain in EPEL, please email me. I will likely take the EPEL branches.
