Can't build PyXML-0.8.4 on RedHat AS-4

I'm trying to build PyXML-0.8.4 on a RedHat AS-4 box.

$ /usr/bin/python -V
Python 2.3.4

$ cat /etc/redhat-release
Red Hat Enterprise Linux AS release 4 (Nahant Update 7)

$ uname -a
Linux korz 2.6.9-78.0.1.ELsmp #1 SMP Tue Jul 22 18:01:05 EDT 2008  
x86_64 unknown

$ gcc --version
gcc (GCC) 3.4.3

When I run "/usr/bin/python setup.py build", it hums along for a  
while, and then I get:


creating build/temp.linux-x86_64-2.3/extensions/expat/lib
gcc -pthread -fno-strict-aliasing -DNDEBUG -O2 -g -pipe -m64 -
