Steps to reproduce:

1. Download attached project (link down in edit below)
2. Open iOSPureBuild script with any text editor (located in the root folder of the project)
3. Modify the script to have correct paths to Unity editor & project
4. Open 'Terminal', cd into the project folder and run the script with ./iOSPureBuild
5. Wait for the script to complete

Expected behaviour: The build succeeds (as it does if you are building manually from Unity editor)
Actual behaviour: The build fails with error "4 errors". Open up 'build_iOS.log' to see the process in more detail.

Note:
Reproduced with iOS, Android and Standalone builds.
Didn't reproduce using the same scripts on an empty project.
