The Sicstus manual says to use this to load a library: use_module(library(Package)). This works in Prolog on the command line, but I can't find out how to load a library from a Prolog source file. When I include "use_module(library(Package))." in my .pl file, I get a permission error: cannot redefine built_in use_module/1.

Try using a directive, such as:

:- use_module(library(Package)).

...at the top of your file, where Package is the atom identifying the library module you want to load.
