See issue ticket, http://rubyforge.org/tracker/?func=detail&atid=21080&aid=27685&group_id=5450. Basically, actionpack-2.3.5 declares a gem dependency of ("rack", "~> 1.0.0") and it tries to load 1.0.1 ver of rack. Looks like there is some incompatibility between rack 1.1.0 and 1.0.1. So loading rack fails and it results in to this error message. The reason Webrick or mongrel works is because they dont have explicit dependency on Rack. Rack ships with webrick and mongrel handlers. so ver 1.1.0 already have all the pieces in place so everything works just fine.
