You need to have GNUstep which you can get from http://www.gnustep.org
To install StepTalk type:

Sripting environment description
Scripting environment description is used to translate the method names and/or
allow or deny the methods for concrete classes. Denying methods can be used to
create safe scripting environment as prevention against script viruses.
- list of methods, that are available for scripting for particular class
- symbolic selector (operator) to selector mapping
- list of modules to be loaded
- list of object finders
Standard vs. full scripting
Before each message send, selector is translated using scipting description.
When standard scripting is used and there is no such selector avilable for
scripting for target object, then an exception is raised. With full scripting,
any message should be sent to any target object.
