I followed your suggestion and opened a bug at:

I agreed that point but it might be a hard work to do. That is because 
OpenSSL in OpenBSD is now 0.9.7j, which doesn't support Camellia. 
However, I will try to port Camellia block cipher to OpenSSL and OpenSSH 
in OpenBSD.

I think it is compatible since there is Camellia source code distributed 
under BSDL and FreeBSD-current has Camellia library inside OS kernel for 

Thank you.
