This isn't a specific answer I'm afraid, but something you may not have thought about.
From your command line snippet, it looks like you're code signing your app bundle after it's been built. Are you moving the bundle (.app folder or maybe an IPA or ZIP file) from another machine, or from another drive? I've had problems with moving app bundles between file systems that don't support symbolic links properly. Are you using a network drive, or have a local drive that's not formatted for Mac OS.
