unknown file I/O primitive: file-acl

I get this problem when using a user emacs to open files as root.

That is, logged in as user but opening files as root thru tramp.

C-x c-f /root@localhost:/etc/exim4/exim4.conf.template

(PS -  seems to default to su - to get root)

Ok, make my edit and attempt to save with C-x C-s, but get this
warning /error or whatever it is:

tramp-file-name-for-operation: \
       unknown file I/O primitive: file-acl

And am unable to save the file.

Has this already been fixed? ... I haven't `pulled' for a couple of
weeks.

I got reams of bunkem googling on this, but not an easy job to tell
what has happened, if anything on this problem.

Tramp supports `file-acl' since version 2.2.7. Emacs trunk includes
Tramp 2.2.10-pre.

I suspect there is an older Tramp version in your way. Check `load-path'.

Best regards, Michael.
