 I saw this today (MacOS 10.6.7 + Aquamacs 23.3.1). I don't have a
 permanent fix, but this workaround works for me. Tramp is using the TMPDIR
 environment to build a path for the ssh control socket. On my system,
 TMPDIR is set to something that looks like:

 /var/folders/Ww/WwhMzsgCFW0-C433VCMqNE+++TI/-Tmp-/

 which results in a path ssh thinks is too long. You can force Aquamacs to
 use a standard TMPDIR by starting it from the terminal like so:

 $ TMPDIR=/tmp open /Applications/Aquamacs.app
