Using putty as a ssh client on FreeBSD

[Josh Paetzel]

I'm trying to use putty on my FBSD 6.1-R box to access another FreeBSD 
box.  I can get in fine using the command line ssh client but when I 
attempt to use putty I get the following error:

Unable to use key file "/usr/home/jpaetzel/.ssh/id_rsa" (OpenSSH SSH-2 
private key)

Can anyone point out to me what I am doing wrong?
