Many bug reports/tickets are posted in the wrong queue, because people don't/can't/won't analyze the actual *cause* of the problem.
If module Foo::Bar is just a wrapper over Foo or a subclass of Foo, the problem might very well be hidden in Foo, way out of reach of the author to whose queue the bug was reported. Same for failures regarding system libraries malfunctioning (libxml2, libcrypto, …) or installed basic utilities with severe bugs (tar, cc, bash, …) for which the author of a module cannot be held responsible. IMHO a CPAN author may expect functional bash/cmd, tar, and cd.
Sometime it is hard to be polite to ticket posters telling your module sucks because it doesn't work on their system, even if Makefile.PL and README specifically state that their system or configuration is not supported because of a very good reason (e.g. DBD::Oracle will not install if there are no Oracle client libraries available: that id NOT the fault of the author/maintainer of DBD::Oracle and it is very well documented. I really understand how it pisses them of if people post tickets like that.
