Hi, I was thinking that it may time to update the GemSpec to support another variable called required_ruby_implementation.  Thus, I filled an enhancement request  <div><br></div><div><a href="https://rubyforge.org/tracker/?func=detail&amp;aid=27269&amp;group_id=126&amp;atid=578" target="_blank">https://rubyforge.org/tracker/?func=detail&amp;aid=27269&amp;group_id=126&amp;atid=578</a></div>

<div><br></div><div>At this time, the GemSpec supports required_ruby_version but says nothing about the implementation.  Also, it may be a good time to start upgrading RubyGems as new Ruby implementation are currently in development or has been released like JRuby.  </div>

As long as RubyGems prevents installation of gems whose<br>

&gt; Any idea how we should flag gems that are MacRuby only like textorize-mr? I<br>
&gt; don&#39;t think the platform flag is legit so I&#39;m not sure what to use.<br>
&gt; Any ideas?<br>
