 I am not an expert here, but there seems to be something wrong with
 your version of 'subprocess.py'.
I use a debian based distro and if I look at my version of
'subprocess.py', the line that is throwing the exception isn't 1024
(raise child_exception), it is 1335

Do you still have the symlink etc in place ?
Or to put it another way, try doing a clean OS install, then install
python 2.7 along with the other required packages to compile Samba and
then try ./configure again.
