[X-Unix] old port for ssh

[M K]

I need an older port of OpenSSH than what comes with Leopard.

I have OpenSSH_5.0p1, I need a version of OpenSSH less than 4.5

<aside> the reason is because my Extreme XOS switch doesn't like the  
new OpenSSH client for some reason.
I do not know why this causes a problem, but it does and it's  
annoying...  :-S
</aside>

How do I remove the current port of OpenSSH?
(I read somewhere that I just need to delete the current file, but  
that doesn't seem right)

Where can I find a really old port so I don't have to compile it  
myself and risk screwing something up?


many thanks in advance.
