Time and again posting the code does help ;)

Sourceforge is (un)helpfully redirecting your request and Python is 
(un)helpfully following. I looks like you can avoid this by using a 
URLopener instead of the FancyURLopener implicitly used by urlretrieve():

>>> 
URLopener().retrieve("http://easynews.dl.sourceforge.net/sourceforge/wxwindows/mxMSW-2.8.10.zip", 
filename="tmp.zip")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3.0/urllib/request.py", line 1476, in retrieve
    fp = self.open(url, data)
  File "/usr/lib/python3.0/urllib/request.py", line 1444, in open
    return getattr(self, name)(url)
  File "/usr/lib/python3.0/urllib/request.py", line 1622, in open_http
    return self._open_generic_http(http.client.HTTPConnection, url, data)

    return self.http_error_default(url, fp, errcode, errmsg, headers)
  File "/usr/lib/python3.0/urllib/request.py", line 1644, in 
http_error_default
    raise HTTPError(url, errcode, errmsg, headers, None)
