Well, I tried to install CPAN::Reporter but got two error during the make test for two of the dependent modules:

How do I know what a test is for and can I fix the bug myself? From what I understand the module is downloaded locally and built, so I should be able to find the offending code and fix the problem. What is the normal process when make test errors occur?
