Sorry to report:

ImportError: DLL load failed: The specified procedure could not be found.



I note that the files in the zip are called intl.dll and iconv.dll, not 
libintl.dll and libiconv.dll.   I copied and renamed the files so that I 
have the files under both names in c:\Python24\Lib\site-packages, but 
the result is the same

FYI:  I am on a Thinkpad.  Very rarely, but not never, I have a conflict 
with the IBM installed python.  The problem arises because IBM chose to 
set PYTHONCASEOK causing confusion if modules have capital letter 
names.  I unset it, but very occasionally the system detects the change 
and resets it.  Very annoying and easy to forget about.   Bit me twice.  
I mention this because if you are not on a Thinkpad, you will never find 
this problem.  On the face of it, I don't see that this little feature 
applies in this case.
