mac snow leopard setuptools stick to MacOSX10.4u.sdk when trying to install python-mysql

when I try to install python-mysql today, I got a number of compilation error or complaining /Developer/SDKs/MacOSX10.4u.sdk not found, like the following:

running build

running build_py

copying MySQLdb/release.py -> build/lib.macosx-10.3-i386-2.6/MySQLdb running build_ext

building '_mysql' extension

Compiling with an SDK that doesn't se开发者_JS百科em to exist: /Developer/SDKs/MacOSX10.4u.sdk

Please check your Xcode installation

However, I already installed latest xcode 4.0, which does include latest GCC and SDK.

I tried to find out where the 10.4u.sdk is specified, but could not find it in the system environment, program source and setuptools source.

I tried to export

export SDK=/Developer/SDKs/MacOSX10.5.sdk

export SDKROOT=/Developer/SDKs/MacOSX10.5.sdk

but still has no luck.

so anyone has any idea where this is specified in Mac Snow Leopard pls?

thx

Check your environment for CFLAGS or LDFLAGS. Both of these can include the -isysroot argument that influences the SDK selection. The other place to start at is to look at the output of python2.6-config --cflags --ldflags since (I believe) that this influences the Makefile generation. Make sure to run easy_install with --verbose and see if it yields any additional insight.
