'Framework not found AudioUnit' when trying to build Audiobus iOS Project

Make Electronic Sound

I am experimenting with Gen and attempting to build the following project in Xcode 5.1.1:

The project needs the Audiobus SDK 1 (https://github.com/eumlab/Audiobus/blob/master/Audiobus.podspec) which I was able to access checking out an earlier version since the current version is 2.1.3. It also needs "The Amazing Audio Engine" (http://theamazingaudioengine.com/).

I got up to Step 9 'Build the Xcode project for the device' in the project instructions but received many Mach-O Linker Errors when building:

I read that these errors are almost always related to Frameworks (built in iOS frameworks) not included in the project so I took a look at the project imports and found a couple of references to #import . I then added the AudioUnit.framework and sure enough, the majority of the errors went away.

I was left with one error:

ld: framework not found AudioUnit
clang: error: linker command failed with exit code 1 (use -v to see invocation)`

This is my problem and I have been unable to get rid of this last error. Contrary to suggestion in the following SO answers, removing AudioUnit.framework and adding CoreAudio.framework didn't help but brought back all the Mach-O Linker Errors shown above:

The following posts didn't help me either:

I have uploaded the project to: https://docs.google.com/file/d/0B3-JRETAp68mZDRJWUg0V0F0WnM/edit?pli=1 . If anybody has the time to take a look and see where I'm going wrong I'd appreciate it.
