When looking at any module, checking the cpan testers matrix, and list of open issues is a sensible first step

Thanks for the advice. In the past I've not done much evaluation of CPAN modules before installing them and trying them out so I thought I'd at least look at the dates...

you shouldn't have too much difficulty implementing this yourself

Given that I have already done it for Twitter, I suspect you are correct but I didn't want to reinvent the wheel code if it was readily available and tested.
