- Because
   - ruby(abi) = 1.8 is provided by ruby-libs, not by ruby and while ruby depends on ruby-libs,
     ruby-libs does not depend on ruby, and it is intentional.

- There can be packages which actually need ruby-libs only. So if the package
   really needs ruby package and ruby is not installed automatically by dependency
   resolver, the rpm should explicitly have "Requires: ruby", however for now
   I don't think this should be written explicitly in wiki.
