Xcode Problem 'No signing identity found' how to fix?

Hi, I am in no way a developer, I just use XCode to compile some applications I use where the latest releases are only available as source code.

Until now I have not had any issue compiling these applications.

However, just recently when trying to compile Boxer from http://www.boxerapp.com/ I am presented with an error that states:

No signing identity found

I do not wish to codesign someone elses' application with my own nonexistent signing identity. Can this pointless function be bypassed so I can build the app sucessfully?
