pip安装cx_Freeze does n

Question

我按照下面的说明在macosx终端上设置cx\u冻结：http://martinfitzpatrick.name/article/cx-freeze-and-pyside-on-mac/

当我键入：pip install cx_Freeze

我只得到一堵墙，以：

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
error: command 'gcc' failed with exit status 1

有什么想法吗？在
