Hello, I've just finished going through the Meet MacRuby video from PeepCode and making the example Twitter client app. When I tried to build and distribute a release of the app to my friend (on Mac OS X 10.5.8) all he got were crashes and errors when he tried to open it. An example of the errors logged to the console can be found at https://gist.github.com/21f82c11499e0da754e5. I built the app for 10.5 x86_64 with MacRuby embedded. Does anyone have any ideas what the issue might be? Thanks Alistair Holt E: alistairholt@gmail.com W: alistairholt.co.uk / http://www.linkedin.com/in/alistairholt
