Mac OS 10.6/Snow Leopard上的Python构建问题

Question

我在Snow Leopard上遇到了构建Python 2.6.4的问题。

操作系统：Mac OS X 10.6
处理器：Yonah CPU，32位
编译器：gcc-4.2.1

更新 I

通过从CFLAGS中删除所有非标准的包含文件和库解决了这个问题（里面有一个uuid/uuid.h）。尽管下面描述的错误仍然存在，但它还是编译成功了，/usr/include/hfs/hfs_format.h:765是个关键点。对于好奇或有资源的人，这里是相关的源文件：

$ cat /usr/include/hfs/hfs_format.h
...
748 #include <uuid/uuid.h>
749 
750 /* JournalInfoBlock - Structure that describes where our journal lives */
751 
752 // the original size of the reserved field in the JournalInfoBlock was
753 // 32*sizeof(u_int32_t).  To keep the total size of the structure the 
754 // same we subtract the size of new fields (currently: ext_jnl_uuid and
755 // machine_uuid).  If you add additional fields, place them before the
756 // reserved field and subtract their size in this macro.
757 //
758 #define JIB_RESERVED_SIZE  ((32*sizeof(u_int32_t)) - sizeof(uuid_string_t) - 48)
759 
760 struct JournalInfoBlock {
761         u_int32_t       flags;
762         u_int32_t       device_signature[8]; // signature used to locate device.
763         u_int64_t       offset;        // byte offset to the journal on the device
764         u_int64_t       size;          // size in bytes of the journal
765         uuid_string_t   ext_jnl_uuid;
766         char            machine_serial_num[48];
767         char            reserved[JIB_RESERVED_SIZE];
768 } __attribute__((aligned(2), packed));
769 typedef struct JournalInfoBlock JournalInfoBlock;
...

我把这个问题留着，因为构建过程中出现了太多警告和这个错误，还是让我有点困惑……

更新 II

为了消除关于部署目标的警告，我在编译前编辑了Makefile：

$ cat Makefile
...
126 MACOSX_DEPLOYMENT_TARGET=10.3 # => 10.6
...

原始问题

在尝试从源代码构建Python 2.6.4时，我遇到了一个错误：

$ uname -v
$ Darwin Kernel Version 10.2.0: Tue Nov  3 10:37:10 PST 2009; \
    root:xnu-1486.2.11~1/RELEASE_I386

$ cd ~/src/Python-2.6.4
$ ./configure --enable-universalsdk=/ --prefix=$HOME
checking for --with-universal-archs... 32-bit
...
checking machine type as reported by uname -m... i386
...
checking for OSX 10.5 SDK or later... no   // <- But I have XCode + the SDKs installed?
...

$ make
...

...
/usr/include/hfs/hfs_format.h:765: error: \
    expected specifier-qualifier-list before ‘uuid_string_t’

这个错误似乎与Python/mactoolboxglue.c有关。欢迎提供线索！

此外，我还收到了很多这样的警告：
