I tried JACAL with guile 1.5.4. To start it, I fired up guile in the
directory where I unpacked JACAL, then loaded the slib module and started
JACAL as described in its manual:

$ guile

guile> (slib:load "math.scm")

type qed() to return to scheme, type help() for help.

However, I got errors when trying to use symbolic variables (e.g. `a+b;').

I had to set JACAL's output grammar representation to "scheme" to get 
it working:

e0 : guile> set outgrammar scheme;

e0 : guile> a + b;

(define e0 (+ a b))

e1 : guile> 

Presumably, there is something in JACAL's infix grammar interpretation code
or the underlying slib, that isn't compatible with guile?

I didn't investigate this further, because I've not started to do any
serious work with JACAL.

HTH you to get started, in case you were experiencing the same error.
