我正在尝试为iOS构建kivy。在tutorial in kivy's guide之后，我输入命令：
$./toolchain.py build kivy
但它会输出此错误消息：
Traceback (most recent call last):

STDOUT:
STDERR:
xcrun: error: unrecognized option: --show-sdk-path
Usage: xcrun [options] <utility> ... arguments ...
Find and execute the named command line utility from
the installed Xcode.
Options:
-h, --help show this help message and exit
-v, --verbose show verbose logging output
--sdk <sdk name> find the tool for the given SDK name
--toolchain <name> find the tool for the given toolchain
-l, --log show commands to be executed (with --run)
-f, --find only find and print the utility path
-r, --run find and execute the utility (this is the default behavior)
-n, --no-cache do not use the lookup cache
-k, --kill-cache remove any existing cache file (and perhaps recreate)
我使用的是Mac 10.8（在vmware上）+ Xcode 4.6。
