openssh unix dev - Mar 2008 - OpenSSH_4.7p1, OpenSSL 0.9.8g Host Key Verification Failed

Greetings,

I am trying to cross compile OpenSSH 4.7 for ppc with QNX Neutrino as my OS.
I have a workstation with QNX on it (x86) and I have linked the utils used
by autoconf to their ppc versions. I have been able to successfully build
sshd/ssh. I copy the binaries built on the x86 to the ppc, and sshd works
great. I can ssh from any machine to it, but when I try to ssh from the ppc
machine to another ppc machine or the x86 machine, I get the error "debug1:
read_passphrase: can't open /dev/tty: No such device or address Host key
verification failed."

If I run it with -vvv, I get (see below):

I am not running Xserver on the ppc, but it is on the x86 machine. Going
through some message boards I have tried setting the DISPLAY environment
variable to DISPLAY=IPAddress:1, but this doesn't change the output. I think
it wants to output to the console that the rsa fingerprint (etc) is new and
i can say yes/no, but this message isnt
making it to the console. If I do an ls -al /dev/tty I get: "crw-rw-rw-  1
0         root         1,   4 Jan 01 01:25 /dev/tty". I have also tried
touch /dev/tty and this returns with "/dev/tty: No such file or
directory".

Any suggestions that you may give will be very helpful. Many thanks.

This would imply that OpenSSH can't find a /dev/tty device.  Do you have 
"Dev.tty" driver running and have you creating your ptys devices on
the
client side?
