----------------------------------------
The reason is that I no longer have llvm-gccnor gccbinaries.
其原因是，我不再有llvm-gcc，也没有gcc二进制文件。
I tried to upgrade XCode from 3.something to 4.3.2, but it din't help. It comes as a simple app and it doesn't populate /usr/binwith llvm-gcc.
我试图将 XCode 从 3.something 升级到 4.3.2，但没有帮助。它是作为一个简单的应用程序，它不填充/usr/bin用llvm-gcc。
What am I doing wrong?
我究竟做错了什么？
