Using b127046831e2, I'm experiencing an import problem during the NumPy build.

I've reduced it to this scenario, which works in 3.2 but not in 3.3.
Note that in NumPy's setup.py, the equivalent of /home/stefan/tmp is 
the first entry in sys.path. I'm not sure if this isolated example is 
terribly useful:


$ pwd
/home/stefan/tmp
$ ls distutils/command/
__init__.py  xyz.py
$ cat distutils/command/__init__.py

distutils_all = ['xyz']
__import__('distutils.command',globals(),locals(),distutils_all)

$ cat distutils/command/xyz.py
$
$ python3.2 distutils/command/__init__.py
$
$ /home/stefan/usr/bin/python3.3 distutils/command/__init__.py
Traceback (most recent call last):
  File "distutils/command/__init__.py", line 3, in <module>
    __import__('distutils.command',globals(),locals(),distutils_all)
ImportError: No module named 'distutils.command.xyz'
