in reply to Error While Installing a Module Telnet.pm
If you change the tests so that they do not fail, are you soving a problem or creating one? If the source of the failure is in the module, then you are very likely creating bigger problems for yourself later on.
The goal is not to have the tests pass, but to have the module work as it should.
If you report your results to the author, you'll take a step towards helping others avoid the same problem, and towards helping the author improve his module.
