Hi,
Just for your information, I have pushed ruby-2.0 branch into the Ruby's git repo. So if you like test the latest Ruby, you need to get the latest HEAD tarball, which could be prepared using:
$ cd /path/to/your/ruby/sources $ ./tool/make-snapshot tmp
Note that you have to have available subversion and bison on your system. Also note that the content of tarball is needed to be repacked, that the Ruby sources will be stored in "ruby-2.0.0-p0" folder (I know, it is annoyance, but you can fix the spec and send me a patch ;). Also note that I currently keep the ruby_abi at 1.9.1, while the official release will have 2.0.0 probably. This should allow you to use Fedora's gems without rebuild. Any comments/patches are appreciated.
Vit
