The same problem occurred again today while attempting to reconfigure my
system (same errors, while attempting to build the same python2-urwid
dependency of wicd).

I wonder why there are so such failures on hydra
(https://hydra.gnu.org/job/gnu/master/python2-urwid-1.3.1.x86_64-linux). I
also wonder why my system is trying to build this package if it already
exists on Hydra. I have both the bayfront & gnu mirror substitute
servers enabled.
