Let me reply to myself. Try to automate a Ruby installation on Debian without using a PPA (like the awesome service that Brightbox is providing everyone at http://wiki.brightbox.co.uk/docs:ruby-ng ) or installing a compiler on your production server.
I don't have a problem with Ruby, I have a problem with its clusterfuck of programs that reinvent the package management wheel and assume that you're going to send your work over to magicland where all of the Ops wizards will make it into a working product.
The reason it's that way is because most of these people develop on Macs then hand off to someone to deploy on Linux. They don't know anything but web dev, and with PaaS like Heroku, they're never likely to. My warning, though: if the reason you're on a PaaS is because you have no idea of how to deploy, you're going to be paying an ignorance tax. Make Ruby easier to deploy, and PaaS will end up cheaper.
edit: I have no problem with rvm (or virtualenv) as a container to run different versions of a language and dependencies on the same server. To use those tools to run a single system version for a single application would be silly, but since the tools are completely broken for doing that anyway, it's simply impossible to do and to retain dark, lush hair at the same time.
