Python 2.7.3 |EPD_free 7.3-2 (32-bit)| (default, Apr 12 2012, 14:30:37) [MSC v.1500 32 bit (Intel)] on win32 
Type "credits", "demo" or "enthought" for more information. 
>>> import distutils 
>>> print distutils.__version__ 
2.7.3 
>>> 

ve C:\Python27\Lib\distutils\core.py hattı yaklaşık 90 görünüyor:

global _setup_stop_after, _setup_distribution 

# Determine the distribution class -- either caller-supplied or 
# our Distribution (see below). 
klass = distclass 
if klass: 
    del distclass 
else: 
    klass = Distribution 

if 'script_name' not in attrs: 
    script_name = os.path.basename(sys.argv[0]) 
if 'script_args' not in attrs: 
    script_args = sys.argv[1:]

Martijn Pieters doğru yorumlarda sonucuna gibi benim Python yüklemem bir şekilde bozulmuş. En son Python sürümünü (2.7.11) kurdum ve şimdi her şey yolunda gidiyor.
