The system cannot load a module compiled by a different version, that's the
problem. You can try to compile the source, if you have it, or adapt the code
to use the very similar standard module (to your version):
'x-oz://system/adt/Stack.ozf'
See documentation at
http://www.mozart-oz.org/documentation/mozart-stdlib/adt/stack.html
The adaptation would go +- like his:
declare STACK_URL = 'x-oz://system/adt/Stack.ozf'
declare STACK_MODULE = {Module.link [STACK_URL]}
declare NewStack = STACK_MODULE.new
Please notice that commands are named a bit differently in this package. For
example, push is called put.
Good luck! Cheers,
Jorge.
