See you in Las Vegas!
Prerequisites
We'll use the stable release of SproutCore (0.9.23) although I plan to address what's different about the 1.0 API which is currently in alpha testing. So to be able to work in the tutorial, you'll need recent versions of Ruby and RubyGems. Follow these directions to install SproutCore.
Note that the SproutCore gem depends on merb-core (>= 0.9.9), erubis, rubigen, and mongrel.
Before the tutorial starts, you must be able to view localhost:4020. If that works, you know everything installed correctly.
This may go without saying, but you also need to have Rails 2.3.x installed. Specifically you should be able to load the Rails startup page on your development machine at http://localhost:3000/.
Recommended Reading
I strongly recommend you complete the "Hello World" tutorial on the SproutCore home page. You may also want to browse the project wiki to get more of a sense of the framework.

Wish I could be there. Good luck!
FYI, I couldn't get the SproutCore server to start up on Leopard due to an extlib compatibility issue. Downgrading that gem, per the thread below worked for me.
SproutCore server startup error
thanks for tracking that down, hope it doesn't bother anyone else. See you soon!
I was successful with installing sproutcore, but am unable to get "hello world" to run. Here's the stack trace:

I have rails 2.3.2 installed as well. This occurred on OSX 10.5.6 using Ruby 1.8.6p114.
Oops, I just saw Aaron's comment about the extlib incompatibility just now.
I get the following error trying to install SproutCore. I'd say it's a compatibility issue with Ruby 1.9. The problem is I installed my Ruby 1.9 by compiling the sources and I can't uninstall it now (there's no "make uninstall"). Any ideas?

Yes, I downgraded to Ruby 1.8.7 and the SproutCore installation worked.
In case it's useful, although everyone is different, this is how I uninstalled Ruby 1.9:
cd /usr/local
sudo rm -Rf lib/ruby
sudo rm -Rf include/ruby-1.9.1/
sudo rm -Rf lib/libruby*
sudo rm -Rf bin/ruby
rm -Rf src/ruby-1.9.1-p0
rm -Rf src/ruby-1.9.1-p0.tar.gz
Then I re-installed Ruby, RubyGems and Rails.
