ssh-askpass 1:1.2.4.1-3 (sparc binary) in ubuntu edgy

under X, asks user for a passphrase for ssh-add
 This is Jim Knoble's free implementation of the ssh-askpass program.
 .
 Jim calls this x11-ssh-askpass, but I've decided to call it ssh-askpass
 to make it easier to find, because this is almost certainly the version
 you want.
 The other two versions from the OpenSSH source are also available if you're
 interested (as ssh-askpass-ptk and ssh-askpass-gnome).
 .
 The non-free implementation is no longer being packaged. Its source is
 still available, as part of ssh-nonfree's source.
