matplotlib and python 2.2

Hi

I'm trying to compile matplotlib on centos3 (redhat el3). it has python 2.2.3
I get a gcc error:

building 'matplotlib._na_cntr' extension
gcc -DNDEBUG -O2 -g -pipe -march=i386 -mcpu=i686 -D_GNU_SOURCE -fPIC -fPIC -I/usr/local/include -I/usr/include -I. -I/usr/include/python2.2 -c src/_na_cntr.c -o build/temp.linux-i686-2.2/_na_cntr.o -DNUMARRAY=1 -O3 -Wall -fPIC -m32 -Wa,--32
src/_na_cntr.c:1701: error: parse error before "init_na_cntr"
src/_na_cntr.c:1702: warning: return type defaults to `int'
src/_na_cntr.c: In function `init_na_cntr':
src/_na_cntr.c:1706: warning: `return' with no value, in function returning non-void
src/_na_cntr.c:1712: warning: `return' with no value, in function returning non-void
src/_na_cntr.c:1716: warning: dereferencing type-punned pointer will break strict-aliasing rules
error: command 'gcc' failed with exit status 1

seems that PyMODINIT_FUNC is unknown.
I added
#define PyMODINIT_FUNC DL_EXPORT(void) in cntr.c
and it compiles.
But, I try to launch a example, I get the same error:

python image_demo2.py
Traceback (most recent call last):

    t = tempfile.TemporaryFile(dir=p)
TypeError: TemporaryFile() got an unexpected keyword argument 'dir'

Is python2.2 no more supported?

Thanks
