我已经通过enthought 7.2软件包安装了python 2.7，我一直在尝试安装pyraf软件包，但每次我尝试安装它时都会得到以下内容：
copying lib/pyraf/wutil.py -> build/lib.macosx-10.5-x86_64-2.7/pyraf
running build_ext
building 'pyraf.sscanfmodule' extension

gcc: error: x86_64: No such file or directory
gcc: error: unrecognized option ‘-arch’
gcc: error: unrecognized option ‘-arch’
error: command 'gcc' failed with exit status 1
所以我认为这是一个架构问题，所以我重新安装了包（i386，XCode），然后得到了这个
running install

copying lib/pyraf/svn_version.py -> build/lib.macosx-10.5-i386-2.7/pyraf

gcc: error: i386: No such file or directory
gcc: error: i386: No such file or directory

gcc: error: unrecognized option ‘-arch’
之后在我看来，真正的问题是gcc版本问题，所以我找了任何安装的gcc，我发现了这个：

所以我决定使用.bash_profile文件中的别名行指出正确的gcc版本，它根本不起作用。
我尝试设置gcc环境并构建pyraf setup.py并得到了这个：
Giotto:pyraf-dev Huguito$ export CC=/usr/bin/gcc-4.2
Giotto:pyraf-dev Huguito$ python setup.py build
running build
running build_py
copying lib/pyraf/svn_version.py -> build/lib.macosx-10.5-i386-2.7/pyraf
running build_ext
building 'pyraf.sscanfmodule' extension

gcc: error: i386: No such file or directory
gcc: error: unrecognized option ‘-arch’
error: command 'gcc' failed with exit status 1
如果我键入gcc命令但没有-arch i386标志：
Giotto:pyraf-dev Huguito$ gcc -fno-strict-aliasing -fno-common -dynamic -isysroot
/Developer/SDKs/MacOSX10.5.sdk -DNDEBUG -g -O3 -isysroot /Developer/SDKs/MacOSX10.5.sdk

I/Library/Frameworks/Python.framework/Versions/7.2/include/python2.7 -c
src/sscanfmodule.c -o build/temp.macosx-10.5-i386-2.7/src/sscanfmodule.o
它似乎编译得很好，但是在重新编译之后它会忽略它并且根本不起作用。
