io.h include file in pyconfig.h

[pythonnewbie]

I am trying to rebuild a rpm that was implemented in the python
language. I installed the python package 2.3.3 from Suse 9.1 Linux CD.
I got the following error when rebuilding the rpm,

/usr/Python-2.3.3/Include/pyconfig.h:30:16: io.h: No such file or
directory

where I should find the correct "io.h" in this linux environment?

Thanks.
