It does contain (among others) /Library/Frameworks/Python.framework/Versions/3.3/include/python3.3m/Python.h (I am using Python 3.3.2)

I have some progress: I reinstalled XCode 3.2.6 after removing the old XCode. And I run the test with the default gcc, which is gcc-4.2 (=version 4.2.1). 

$ gcc-4.2 -v
Using built-in specs.
Target: i686-apple-darwin10
Configured with: /var/tmp/gcc/gcc-5666.3~6/src/configure --disable-checking --enable-werror --prefix=/usr --mandir=/share/man --enable-languages=c,objc,c++,obj-c++ --program-transform-name=/^[cg][^.-]*$/s/$/-4.2/ --with-slibdir=/usr/lib --build=i686-apple-darwin10 --program-prefix=i686-apple-darwin10- --host=x86_64-apple-darwin10 --target=i686-apple-darwin10 --with-gxx-include-dir=/include/c++/4.2.1
Thread model: posix
gcc version 4.2.1 (Apple Inc. build 5666) (dot 3)

On my previous test I used 

$ export CC=/usr/bin/gcc-4.0
$ export CXX=/usr/bin/g++-4.0

as recommended in http://scipy.org/scipylib/building/macosx.html, but maybe this recommendation is outdated as the Python is compiled with gcc version 4.2.1

Now there is only one error left:

ERROR: test_big_arrays (test_io.TestSavezLoad)

That's the one you mentioned I think.
