mac os x 10.6.7，MacOSX10.6.sdk环境下编译toolchain

有没有人在mac os x 10.6.7或8，MacOSX10.6.sdk环境下编译通过toolchain?下载了一个代码，编译了一把，编译不通过：In file included from ../../../odcctools/include/libkern/OSByteOrder.h:70,
  from ../../../odcctools/include/mach/ndr.h:94,

按照网上的修改：export INCPRIVEXT="-isysroot /Developer/SDKs/MacOSX10.6.sdk" 再编译，错误依然
