password authentication works

it was built with support for the following:

-r1 is gentoo-specific

this is an amd64-box

The key looks to be corrupt in some way (ssh-keygen can't parse it either).
OpenSSH -current will more gracefully handle such broken keys and not terminate
the connection when it encounters them.

Could you check that the public key is not damaged? You can regenerate the
public key from the private key using "ssh-keygen -yf /path/to/private.key"

seems like the key is correct, keygen built exactly the same again
