This is ugly, I don't know of any short cuts. "testing" means run your program exercising all Tk windows and widgets then see where program generates run time warning. The Perl can find lots of stuff by just "use Tk" in a script form that it can't find in the .exe form.

Anyway from my experience with this, it is an iterative process. But it doesn't take long as error message will give you a clue as to what is missing.

Now when I'm writing the code for something that will be in a .exe file, I just add a "use" statement for every different Tk widget that is used in the code. I usually miss one and have to go back and add it.
