在OSX上从源代码编译了gdb之后，我想调试Mach-O应用程序。但是，打开Mach-O二进制文件时，显示以下错误：
"/Users/nlykkei/Projects/test": not in executable format: file format not recognized
我知道port（MacPorts）可以下载Apple版本的GDB，但是它的版本太旧了。
如何配置gdb，以便它能够识别Mach-O二进制文件？
完整输出：
nicolass-mbp:gdb nlykkei$ ./gdb ~/Projects/test
Python Exception <type 'exceptions.ImportError'> No module named gdb:
./gdb: warning:
