Hello why does zip from srfi-1 not work?

(write (zip (list 1 2 3) (list 2 3 4)))

gives:

== *** ERROR IN map -- Operator is not a PROCEDURE (#!unbound '#<procedure #2 procedure?> '#<procedure #3 list> '#<procedure #4 map>) ==

I downloades srfi-1 from snow. However, cannot install it but using srfi-1-reference which comes with snow:

== gsc -link srfi-1-reference.scm test.scm gcc srfi-1-reference.c test*.scm -lgambc ./a.out ==

Btw: Is there a way Gambit to obtain better error messages?

Thanks, Siegfried Gonzi
