Help ctypes on arm linux not compile

I have built python 1.5.1 from source for an embedded ARM9 debian
linux Sarge distribution but
ctypes doesn't build. Anybody have any idea what the problem is? Do
I have to have the libffi package
installed.
See my errors below.
I looked and ffi.h exists in three places
/usr/local/src/Python-2.5.1/Modules/_ctypes/libffi_arm_wince/ffi.h
/usr/local/src/Python-2.5.1/Modules/_ctypes/libffi_msvc/ffi.h
/usr/local/src/Python-2.5.1/build/temp.linux-armv4l-2.5/libffi/
include/ffi.h
with two different definitions for ffi_closure
typedef struct {
char tramp[FFI_TRAMPOLINE_SIZE];
ffi_cif *cif;
void (*fun)(ffi_cif*,void*,void**,void*);
void *user_data;
} ffi_closure __attribute__((aligned (8)));
typedef struct {
char tramp[FFI_TRAMPOLINE_SIZE];
ffi_cif *cif;
void (*fun)(ffi_cif*,void*,void**,void*);
void *user_data;
} ffi_closure;
is the __attribute__ syntax causing a problem
building '_ctypes' extension
