Debugging a Rails 3 app with RadRails 2?

When trying to debug a Rails 3 app with RadRails 2.0.4, I'm running into a problem with gem loading, apparently. See below for a stack trace. That problem disappears, when I move Gemfile out of the way, but, of course, then other necessary gems aren't loaded.

Project: <myproject> File: script/rails Working Directory: /home/michael/aptana/<myproject> Interpreter Arguments: -e STDOUT.sync=true -e STDERR.sync=true -e load(ARGV.shift) Programm Arguments: server --debugger --environment=development -- port=3000 Interpreter: standard /usr/bin/ruby

I've tried adding/removing ruby-debug and ruby-debug-ide to the Gemfile in any order and at the top-level as well as in the :development group.

I think, but are far from sure, that RadRails and Bundler are of devided minds as to which gems are active when. First, RadRails directly runs rdebug-ide, which runs script/rails which causes bundler to mangle which gems are active. In the file, where the error occurs, there's a

require 'ruby-debug/processor'

and that succeeds. But possibly it loads the wrong file, i.e. not the one from ruby-debug, but the one from ruby-debug-ide. The later does indeed not define Debugger::CommandProcessor. (I'm using Ruby 1.8.7 and this might matter here.)

I've tried my luck with the latest beta of Aptana Studio 3 as well, but that wasn't a pleasant experience, either.

I'm hoping someone has an idea how to get around this problem. I'm also taking suggestions for other Linux-based(!) IDEs with suitable debugging abilities :frowning:
