I'm not sure that reviving some six year old thread is the best apporoach to get an answer from Juerd about the module. I'm not privy to metaperls intentions, but if they are to get bugs fixed, the approach taken strikes me as somewhat odd. The bugs are not reported via the traditional bug reporting venue, rt.cpan.org, but hidden in the last point of the post, seemingly copied from some other email without showing care about the formulation. Metaperl is aware of the traditional venue for reporting bugs. If there is doubt in whether RT is used by Juerd, maybe that question could have been cleared by email.
If the intent is to take over maintenance of the module, metaperl should maybe have mentioned that as a constructive way of resolving the issue.
I get the impression of an air of entitlement of metaperl to a speedy response, as metaperl mentions lack of reaction within 48 hours multiple times. I'm not sure this sense of entitlement or disregard for the personal situation of Juerd (whatever it might be) warrants anything else than mocking. And, on a more serious side, if you really need an SLA with a reaction time below 48 hours after reporting an error, I think you will need to talk to the author about arranging such an agreement with compensate remuneration.
