Errors in i2 code?

I recently tried to get i2 running. Grabbed it from rubyonrails.org/svn,
but Rails is throwing numerous errors when running the app (even just
running script/console fails due to an error in routes.rb relating to
using a regex in a route command). It seems that it might be deprecated
code that no longer works with current Rails, but before delving into it
and trying to fix it or get it working, I was wondering if anyone else
has experienced the same or has a working copy of the code. Or maybe it
works just fine and I’m just doing something stupid.
