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?

No, but I'm having the same issue with one of my users. Any news in that regard yet? I believe this is identical with http://www.macruby.org/trac/ticket/354, yes? My user's on 10.5.8 as well, I've built for 10.5 x86_64, MR 0.5 embedded & compiled. Here's his full bug report: --- snip --- Dyld Error Message: Library not loaded: @executable_path/../Frameworks/MacRuby.framework/Versions/0.5/usr/lib/libmacruby.dylib Referenced from: /Applications/Ephemera.app/Contents/MacOS/Ephemera Reason: no suitable image found.
