If you see this error - it may be due to the fact you installed Rails 2.3.5 a while ago and you do not have 1.0.1. Even after installing the latest rack gem, this error may persist.
Here are many people with the same issue

I got around this by uninstalling rack and rails 2.3.5. When I reinstalled rails, it included the rack dependency.
