But with pre-0.9, you can fix the radiant gem spec: <your ruby installation>/gems/1.8/specifications/radiant-0.8.2.gemspec Change the line: s.add_runtime_dependency(%q<rack>, [">= 1.0.0"]) to: s.add_runtime_dependency(%q<rack>, [">= 1.0.0","< 1.1.0"]) This did the trick for me. I can't uninstall rack 1.1.0 as I need it for another Rails app. Ringo
