        All three versions provide the same output, unless I did some

        since I did not tested it (actually the middle one was taken
        directly
        

        from rubygem-POpen4.spec). So which version you prefer? Please
        note that
        

        the "gem install" will always "unpack" the gem with some
        additional, for
        

        our case unimportant, steps. We do not distribute the .gem file
        anywhere.
        

      You didn't exactly (directly) answer my question.  Pretend I don't
      know much about ruby... (not far from the truth).
      

      So, for rubygem packages that include native (C or otherwise
      code), how and when is this compiled?  If it is always done so
      during either version of these guidelines, please do accept my
      apologies for being ignorant.
      

    It is compiled during the "gem install" step. So "gem install" is
    doing %prep, %build, %install in one step. So yes, it is always done
    for either version of guidelines.

    
      However, you do say you do not distribute the .gem, though I'm
      curious why this seem to contradict you:
      

      rpm -qlp rubygem-POpen4-0.1.4-3.fc17.noarch.rpm
      

      /usr/share/gems/cache/POpen4-0.1.4.gem
      

      ...
      

    I knew you will point it out :).

    
    It is cached version of the original gem, which RubyGems may use to
    restore the gem into its original state (and may be other unknown
    purposes). However, it is not used in runtime, nor it is good idea
    to restore the gems maintained by RPM by gem command. Moreover, even
    though the gem would not be available in the cache dir, RubyGems
    will download it. Hence we add new clause into the packaging
    guidelines:

    
    Since the Gem is installed using RPM, you must exclude the
    .gem file.
