sudo pacman -Syu today, I found that both zeus and urxvt
broke. I use urxvt as my terminal, and at first I was at a loss as to how to
troubleshoot, till my coworker pointed out I could just run
zeus breaks with "exit status 1" and then just hanging.
urxvt breaks with "urxvt: can't initialize pseudo-tty, aborting"
In both cases, when I downgraded
glibc to 2.17-6 the problem was fixed. I
needed to also downgrade
binutils to 2.23.2-2.
Also, to fix zeus, the json gem needed to be upgraded to 1.8.0.
