Guidelines: Requires: ruby

Hi all, I have a small question regarding Ruby guidelines in Fedora described on this page: http://fedoraproject.org/wiki/Packaging/Ruby I recently installed ruby-libguestfs package on my Fedoras (both; 13 and 14) and this package didn't pulled ruby package, although it is not usable without it. https://gist.github.com/659706 ruby-libguestfs has only "Requires: ruby(abi) = 1.8" in spec file as described in guidelines. Two questions: 1. Why the runtime isn't pulled? (only ruby-libs are installed – is this intentional?) 2. Shouldn't we also add a section to that wiki page mentioning adding "Requires: ruby" to spec file? Thank you in advance for clarification! --Marek
