You may want to try the Graphical Debugger. It's written in Perl/Tk and has saved my bacon numerous times.

You can watch your variables as your program executes - which is what I assume you wanted to do with the print statements you don't want to liberally sprinkle all across your program. The really nice thing is that you can also contract or expand arrays, hashes and complex data structures so you can see how they're being modified.

Good luck!
