No response, so I'm closing the bug. Feel free to reopen if it doesn't
work for you.

Best regards, Michael.

On FreeBSD, if tramp-own-remote-path is a member of, then using tramp's
sudo method raises an error similar to:

    byte-code: `/bin/sh -l -c 'echo 9905dea968fdd4a549d307a722e8109b \"$PATH\"'' returns with error

On FreeBSD, /bin/sh does not accept the -l flag.  bash, dash, and ksh
do, but that's not part of the POSIX shell requirements (see 
http://pubs.opengroup.org/onlinepubs/009695399/utilities/sh.html), and
historically the Bourne shell doesn't.

This can be traced to tramp-get-remote-path, where it sends the command
"%s -l %s 'echo %s \\\"$PATH\\\"'", where the first %s is the shell.

I typically remove the -l flag in that function to make my Emacs work.

Again, this only applies if tramp-own-remote-path is a member of
tramp-remote-path; otherwise, that part of the code isn't invoked.  It's
not there by default, but it's very useful.
