What is your python version? It looks like the macro PyMODINIT_FUNC
is not being found. This is defined in pyport.h in python2.4, but you
probably have a much older python installed. The reason you cannot
find _na_cntr.c is that it is autogenerated to support Numeric or
numarray at compile time. The src dile is src/cntr.c. In that file,
try replacing

PyMODINIT_FUNC

  with

extern "C" void

  or perhaps

DL_EXPORT(void)

and let me know if this helps

Yes, it is python 2.2.

I suspected as much.

Hmm, neither of these work - pretty much the same error:

gcc -DNDEBUG -O2 -g -pipe -march=i386 -mcpu=i686 -D_GNU_SOURCE -fPIC -fPIC -I/usr/local/include -I/usr/include -I/usr/include/python2.2 -c src/_na_cntr.c -o build/temp.linux-i686-2.2/_na_cntr.o -DNUMARRAY=1

src/_na_cntr.c:1698: parse error before string constant

I suspect that supporting such an antique distro will be more trouble than it is worth. It would probably be easier for me to upgrade the machine.

Cheers
