Jeremy: I've had success getting HPN-SSH patch to apply to openSSH.org's source downloaded into 9.10 and installing. Perhaps you make a package from those sources? Note: I found it critical to use the right HPN patch for the right SSH version. Also, the openssh.org soruce install will install the binaries to slightly different locations than the ubuntu package.
