Hi,
I think it is Python related as I did a grep of my Python versions 
installed from source for this function and got:
python2.5/distutils/sysconfig.py:def _init_posix():
python2.6/distutils/sysconfig.py:def _init_posix():
python2.7/sysconfig.py:def _init_posix(vars):
python3.1/distutils/sysconfig.py:def _init_posix():

I have not had time to check why Python2.7 is different from the other 
versions (both location and call).
