I have successfully gotten Tramp to work with a fink-built FSF Emacs
under OS X by using a process-connection-type of nil and a Tramp
connection method of sshx.  It was not necessary modify the stock
definition of sshx.

I use SSH Agent (http://www.phil.uu.nl/~xges/ssh/) to handle ssh proxy
authentication so that ssh-askpass/ssh-add is never in the loop.
