If you provide anything separate from the .APP file, you must make sure to distribute the compiled version of the program - from reading your message, you're trying to access code that's not being built into the .APP file. Compiling a .PRG results in a .FXP, so you'd need to provide the .FXP rather than the .PRG as the external module.
