Could you report what happens with
sage: import urllib
sage: urllib.urlretrieve('http://www.sagemath.org//spkg', 'test.html')
('test.html', <httplib.HTTPMessage instance at 0x47788c0>)
sage:
? This should write a file test.html in the current directory.
Just to be sure, is
http://www.sagemath.org//spkg
accessible from a browser?
