Thanks for looking into this.  I am using the scpc method.  The
local machine is a Mac (10.7) and the remote machine is linux
(fedora 15).

Here is the backtrace:

Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p nil)
  logand(nil 73)
  executable-make-buffer-file-executable-if-script-p()
  run-hooks(after-save-hook)
  basic-save-buffer()
  save-buffer(1)
  call-interactively(save-buffer nil nil)

emacs version:

GNU Emacs 23.3.1 (x86_64-apple-darwin11.2.0, GTK+ Version 2.24.6)
