I have receieved a handful of fail reports and rt resports from cpan testers and rt.cpan.org. I get lots of bug reports from non-perl users for autodia so its water off a ducks back to me. But its valuable nonetheless.
Usually I will try and fix any problem straight away, but because cpan-testers is pretty automated I know that if any showstopper stops my code from installing or compiling it should usually get caught and reported back to me.
I'd really like to say thanks to barbie and the cpan-testers, they have ensured that my code is more likely to compile and install on places I either can't or just can't be bothered to to test it.
