[MacRuby-devel] Class MacRuby implemented in two locations

I figured out my issue. I had a buggy script running on a second thread which wasn't reporting the error. Is there a way to have a second thread throw an error back to Xcode when something goes wrong?

	  NSThread.detachNewThreadSelector('control_server:', toTarget: self, withObject: 'dummy')

I am still getting the "Class MacRuby is implemented in both..." error, although it doesn't seem to be breaking anything. Is this something I should worry about?

Hi Everyone,

I am getting a strange error when I try to build a project. I made some minor changes to an application and now when I build the app I am getting this message:

objc[5058]: Class MacRuby is implemented in both /Library/Frameworks/MacRuby.framework/Versions/0.11/usr/lib/libmacruby.dylib and /Library/Frameworks/MacRuby.framework/Versions/0.11/usr/lib/libmacruby.dylib. One of the two will be used. Which one is undefined.
objc[5058]: Class MacRubyDebuggerConnector is implemented in both /Library/Frameworks/MacRuby.framework/Versions/0.11/usr/lib/libmacruby.dylib and /Users/shaun/Library/Developer/Xcode/DerivedData/Eos_Kids_Kiosk-bmxdeyuthjvgxchcwptzlmfrxpil/Build/Products/Debug/Eos Kids Kiosk.app/Contents/MacOS/../Frameworks/MacRuby.framework/Versions/Current/usr/lib/libmacruby.dylib. One of the two will be used. Which one is undefined.

The project builds fine and runs on my computer. When I deploy it it is only 28MB (I seem to remember the apps being about 50MB with MacRuby embeded) and it crashes on the computer I am deploying to. In the console log on the other computer I get a "Job appears to have crashed: Abort Trap" error message. 

I think my framework isn't embedding properly but I can't see where the problem is in the Xcode Setup. Any suggestions on where to start looking?
