I get what you are trying to say, but I think you're gonna have a hard time saying that Ruby is as easy to deploy "right" as PHP. Rsyncing a bunch of PHP files is a single shell command. Writing puppet or bcfg2 specs to deploy your six-tier web stack for your RoR app is a bit harder, it is most certainly not a button click out of the box, and neither process is necessarily more "right". It certainly helped the PHP ecosystem that deploying a LAMP stack is as easy as running three package installs and copying over some PHP files. The fact that a simple-to-understand, well-established process will scale you up to decent load before you need to get fancy will continue to make it an attractive platform.
