hmmm.  utils_wrap.c has:

/* Python.h has to appear first */
#include <Python.h>

and make correctly includes -I/usr/include/python2.4,
gcc -I/usr/local/src/grass/svn/releasebranch_6_4/dist.i686-pc-linux-gnu/include  -ggdb -march=pentium4 -Wall -Werror-implicit-function-declaration    -fPIC   -DPACKAGE=\""grasslibs"\" -fPIC -I/usr/include/python2.4 -I/usr/include/python2.4    -DPACKAGE=\""grasslibs"\"  -I/usr/local/src/grass/svn/releasebranch_6_4/dist.i686-pc-linux-gnu/include -o OBJ.i686-pc-linux-gnu/utils_wrap.o -c utils_wrap.c
utils_wrap.c: In function 'pyseq_to_ptr':
utils_wrap.c:2496: error: 'Py_ssize_t' undeclared (first use in this function)
utils_wrap.c:2496: error: (Each undeclared identifier is reported only once
utils_wrap.c:2496: error: for each function it appears in.)


but /usr/include/python2.4/ headers only mentions 'Py_ssize_t' in a
comment of pymem.h.
In python 2.5 include files it is defined in pyport.h.

so (IIUC) swig 1.3.29 requires python >= 2.5 ?
