无法使用Kivy工具链编译iOS的第三方程序包

Question

I am working on a small testing project and wanted to add Robot Remoteserver onto an iOS device but can't get toolchain to build the package successfully. Here's the errors I get when I attempt to build this package:

For the line Could not find platform dependent libraries I did set the PYTHONPATH but still had this error.

Since there's no template to follow for the build script, I viewed the build files for the packages kivy comes with and created one that contains the following

from toolchain import PythonRecipe

class RobotRemoteServer(PythonRecipe):
    version = "master"
    url = "https://github.com/robotframework/PythonRemoteServer/archive/{version}.zip"
    depends = ["python"]


recipe = RobotRemoteServer()

I have ensured Kivy and the packages it depends on are all installed correctly. I've also searched the web but can't quite figure out what the problem is. I'm using Xcode 6.4 and latest kivy pull from git. I have been stuck on this for a few days and appreciate any help or guidance.

Kivy recipes follow the same format as those for python-for-android . Here you have the related documentation.
