我需要让Theano在我的Mac上运行以进行学校项目。我从here（表格的第一行）下载了源代码，并将未处理的文件放在我学校项目的库中。我不知道这是否足够，所以我也使用pip install Theano。自从我得到这个以来，一切似乎都很好：
You are using pip version 6.1.1, however version 7.0.0 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
Requirement already satisfied (use --upgrade to upgrade): Theano in ./anaconda/lib/python2.7/site-packages/Theano-0.7.0-py2.7.egg
Requirement already satisfied (use --upgrade to upgrade): numpy>=1.6.2 in ./anaconda/lib/python2.7/site-packages (from Theano)
Requirement already satisfied (use --upgrade to upgrade): scipy>=0.11 in ./anaconda/lib/python2.7/site-packages (from Theano)
如你所见，我正在使用Anaconda。
然而，当我在python控制台中运行测试时，我收到了这些消息：
>>> import theano
WARNING (theano.configdefaults): g++ not detected ! Theano will be unable to execute optimized C-implementations (for both CPU and GPU) and will default to Python implementations. Performance will be severely degraded. To remove this warning, set Theano flags cxx to an empty string.
>>> theano.test()

有什么问题吗？ Theano及其编译器安装得好吗？ 我尝试了this tutorial的第一个例子，并且没有任何错误也有相同的结果。但我想知道如果我使用更复杂的函数和类是否会有任何错误。
