The relevant lines were probably:
Once you've got hold of the $DIFF function, I'm also not sure that your
two "eval" lines are going to work. You see, you haven't told the
interpreter "I" to change the current package to MAXIMA. As such, I
think that
LispObject x = I.eval("'$x");
will work by first reading the string "'$x" to the lisp form
(QUOTE CL-USER::$X)
and then evaluating, to get the symbol CL-USER::$X. However, you want
the symbol MAXIMA::$X. Presumably the Interpreter object has a method to
change package?
