[gambit-list] Newbie: define-macro question

I'm rather new to Lisp & Scheme (< 3 months total exposure) but I'm
trying to make a real effort to learn the language. I'm delving into
macros and having a problem understanding the basics.
I've defined a macro called print-line like so:
(define-macro (print-line msg)
(list `(display ,msg) `(newline)))
When I try to use the macro from the repl I get the error message:
***ERROR in (console)@38.1 -- Operator is not a PROCEDURE
I do see the output I expect prior to the error so something is
partially working. I'm certain that the problem is caused by my flawed
understanding of how macros work. Could someone with more scheme-fu shed
light on what/where the problem is?
