I tried to run the Peepcode Sinatra part of the Shotgun tutorial (lets you skip rebooting your web server for every change you make). The error triggered the following message:
$ shotgun simple.rb / Library / Ruby / Gems / 1.8 / gems / shotgun-0.8 / bin / shotgun: 115: undefined methoddefault 'for Rack :: Handler: Module (NoMethodError) from / usr / bin / shotgun: 19: inload 'from / usr / bin / shotgun: 19
I tried updating the system, mongrel and more, but to no avail.
