Using various emacs:

1. emacs-24.4

emacs-24.4 -Q -L /path/to/tramp-2.4.1/lisp <RET>

Error: "Symbol's function definition is void: cl-struct-define"

2. emacs-25.3

emacs-25.3 -Q -L /path/to/tramp-2.4.1/lisp <RET>

Works.

3. emacs-26.1

emacs-26.1 -Q -L /path/to/tramp-2.4.1/lisp <RET>

Error: "Invalid function: with-mutex"

4. emacs-27.0.50 (master)

src/emacs -Q -L /path/to/tramp-2.4.1/lisp <RET>

Error: "Invalid function: with-mutex"

Tramp works if we use the tramp package that comes with emacs-27.0.50,
via

src/emacs -Q <RET>
M-x load-library <RET> tramp <RET>



Best wishes,

Colin.
