Hi, 
I've downloaded it and tried to start the blog example but got a problem:

.../../lib/nitro/server/shaders.rb:156:in `require': No such file to load -- xml/xslt (LoadError)


I'm on debian, and I have installed all xml related packages, amongst others:

  libxml-ruby1.8 libxslt-ruby1.8 librexml-ruby1.8

but it didn't correct the problem

Any idea?

Btw, it's great to see the cross pollination happening with Ruby on Rails.
