Greetings.

I am following Stack instructions for Moodle. http://moodle.localdomain/question/type/stack/doc/doc.php/CAS/Optimising_Maxima.md

The instructions say:
"
In Maxima, type the commands:
    load("maximalocal.mac");
    :lisp (sb-ext:save-lisp-and-die "maxima-optimised" :toplevel #'run :executable t)
"

Unfortunately the second command produces a "no scavenge function" error. Please see below.

Would be grateful for your help.

Best wishes
