OSX ssh_askpass

I recently received this error on OSX when trying to ssh:

$ ssh me@somewhere
ssh_askpass: exec(/usr/libexec/ssh-askpass): No such file or directory
ssh_askpass: exec(/usr/libexec/ssh-askpass): No such file or directory
ssh_askpass: exec(/usr/libexec/ssh-askpass): No such file or directory
$

I had earlier used a 'sudo screen' to connect out a serial port. Somehow, the permissions on /dev/tty got hosed and ssh thought I wanted to authenticate using a graphical interface; bringing up a new terminal window solved the problem.
