You don't state your exact platform, but the filename quoted is a
Python natively is case-sensitive. Windows 9x and later, and OS/2 with
HPFS file systems, are case-insensitive but case-preserving. So Python
relies on the case preservation when trying to match a filename to a
module name. This behaviour can be turned off with the PYTHONCASEOK
I would hazard a guess that either:-
a) you have the PYTHONCASEOK environment variable set when you shouldn't;
b) you have Python installed on a non-case-preserving file system (like
FAT12 or FAT16); or
c) you installed Python with tools that didn't preserve the case of the
files in the Python library.
