J'ai standard ruby-head et Rails 3.1rc4. J'ai installé ruby-debug avec les instructions suivantes tirées de http://dirk.net/2010/04/17/ruby-debug-with-ruby-19x-and-rails-3-on-rvm/
Mais quand je lance rails s --debugger
il va jeter cette erreur étrange
/Users/schovi/.rvm/gems/ruby-head/gems/activesupport-3.1.0.rc4/lib/active_support/dependencies.rb:237:in `require': dlopen(/Users/schovi/.rvm/gems/ruby-head/gems/linecache19-0.5.12/lib/trace_nums19.bundle, 9): Symbol not found: _ruby_current_thread (LoadError)

Une idée? Merci David
