My share is only 10 man hours, payed for by the US government at a scientist
salary. :-)

A simple patch with a start is attached. Example:

% ./python 
Python 2.5b1 (r25b1:47027, Jun 26 2006, 03:15:33) 
[GCC 4.1.0 20060304 (Red Hat 4.1.0-3)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import foo
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named foo
  Note that subdirectories are searched for imports only if they contain an
  __init__.py file. See the section on "Packages" in the Python tutorial for
  details (http://www.python.org/doc/tut/).
>>> 


The "No module named" message is repeated in these files (2.5b1 tree):

./Demo/imputil/knee.py
./Lib/ihooks.py
./Lib/modulefinder.py
./Lib/xmlcore/etree/ElementTree.py
./Lib/runpy.py
./Lib/imputil.py

If there is a consenus, I'd create a new exception ImportErrorNoModule(name)
that is used consistently from all places. This would ensure uniformity of the
message in the future.
