Thanks. That's far more helpful.
Yet,  I do not seem to have a package 'Solver'. If I do
load(Solver)$
I get
file_search1: Solver not found in file_search_maxima,file_search_lisp.
 -- an error. To debug this try: debugmode(true);

Can you tell me where to get this package?
The implementation I have returns this version information:

Maxima version: "5.32.1"
Maxima build date: "2014-01-21 16:47:24"
Host type: "x86_64-unknown-linux-gnu"
Lisp implementation type: "CLISP"
Lisp implementation version: "2.49 (2010-07-07) (built 3507401929)
(memory 3599308048)"
