Can& #39;t install Orange :«ошибка :команда & #39;clang& #39; не удалось со статусом выхода 1 »

Я пытаюсь установить Orange на свой Mac OS X 10.7.3 (Лев )и я продолжаю получать сообщение об ошибке при использовании либо pip, либо сборки из исходного кода. Во-первых, я получал сообщение об ошибке:

error: command 'gcc-4.0' failed with exit status 1

У меня есть Xcode 4, который поставляется в комплекте с gcc 4.2.1. Поэтому я установил 64 -бит/32 -бит Python 2.7.3 со встроенным gcc 4.2.Я также пытался переопределить выбор компилятора, используя:

export CC=gcc-4.2

Но это привело к другой ошибке:

gcc-4.2 not found, using clang instead
...
error: command 'clang' failed with exit status 1
