Problem noticed by Bug Hunting via PR#42609.
At the moment, MASTER_SITES is commented out.
Although it is linked from HOMEPAGE, but only have very old version now.
(and tarball from http://pypi.python.org/pypi/urlgrabber is checksum mismatch).
urlgrabber is a pure python package that drastically simplifies
the fetching of files. It is designed to be used in programs that
need common (but not necessarily simple) url-fetching features.
It is extremely simple to drop into an existing program and provides
a clean interface to protocol-independant file-access. Best of all,
urlgrabber takes care of all those pesky file-fetching details,
and lets you focus on whatever it is that your program is written
to do!
