It was a weird setting of the variable ``temporary-file-directory'' in
Neil's Macport setup, plus the assumption by tramp that that setting was
valid for the remote - that turned out to be a bad assumption. Not sure
it's worth it for tramp to provide a way to customize that, but that's
your decision :-) AFAIAC, /tmp should be a universal standard.
