Speech in Runtime

This script works when run from MacPerl,

use Mac::Speech;

SpeakString "Hello";



but when I save it as a runtime it gives me an error 

# Can't locate Mac/Speech.pm in @INC.
File 'Santa Iron:Desktop Folder:testinput-'; Line 1
# BEGIN failed--compilation aborted.
File 'Santa Iron:Desktop Folder:testinput-'; Line 1


I hope there is an easy fix.  I have checked the FAQs that came with MacPerl and many of the online resources pointed to by various pages and haven't learned how to include the functionality in the runtime.

I'm guessing there is some line of code I need to include after the 'use' command, but am unsure. Help is appreciated, thanks!
