The best way to solve this is to run the test manually (or in verbose mode), read the output, find the failure, fix it as easily as possible, and send a patch to the author. You might also check the CPAN Testers link for the module from http://search.cpan.org/, though it has no results in this case. Failing that, send the verbose output to the author along with the output of perl -V, and work with him to perform additional debugging.

(I'm pretty sure you already knew this, so I'm posting for the benefit of readers who didn't.)
