First a general comment: This is the wrong forum for bug-reports.
Please send bug-reports to bug-guile.

Array support is implemented in C in Guile. `array-map!' exists but
is named `array-map'. I've now added the name `array-map!' to the
distribution. Meanwhile, you can add a line defining this name to
jacal.scm (see below).

You used the first version of jacal.scm which was broken. (Note that
this was just something I quickly wrote down to illustrate the idea of
a jacal hook.) Please try the new version included below.

I don't know yet what the problem is here. What you see above is
jacal itself reporting an error using slib:error. This may be a bug
in jacal. We have to track this one down.

This is a serious bug in Guile's unmemoization code. Thanks for
finding it! It will hopefully be gone in next Guile snapshot.
OK, poor guy. Do you dare to try it again after finding three
independent bugs? Here's the new jacal.scm:
jacal.scm:
----------------------------------------------------------------------
(define-module (jacal) :use-module (ice-9 slib))
(define-module (ice-9 slib))
(if (defined? 'array-map) ; Workaround for Guile-slib incompatibility
(define-public array-map! array-map))
(define horner #f) ; Workaround for a bug in Jacal
(define-module (jacal))
(slib:load "jacal/math.scm")
(define-public math math)
----------------------------------------------------------------------
