Eddy Verbruggen Calendar Plugin - Failure Help

I am trying to demo the Eddy Verbruggen Calendar Plugin. I created a blank project (myApp), and per the Plugin Instructions I completed the following Steps:

(1) $ cordova plugin add https://github.com/EddyVerbruggen/Calendar-PhoneGap-Plugin.git
(2) and run this command afterwards: $ cordova build

I receive the following error:

The following build commands failed:
CompileC build/myApp.build/Debug-iphonesimulator/myApp.build/Objects-normal/i386/Calendar.o myApp/Plugins/nl.x-services.plugins.calendar/Calendar.m normal i386 objective-c com.apple.compilers.llvm.clang.1_0.compiler
(1 failure)
Error: /Users/stellar/desktop/myApp/platforms/ios/cordova/build: Command failed with exit code 65

at Process.ChildProcess._handle.onexit (child_process.js:823:5)

Any advice on how to proceed?
