OK, I tried to install it at the CPAN prompt by typing install Bit::Vector::Overload. The first thing I saw was something like 'LWP not available, using Net::FTP'. Since we got such different results hopefully some of the other Monks can help you further, but my instinct is that the code is an error message from the server.
As an aside, Bit::Vector::Overload didn't install for me either because of dependencies on other modules I don't have, but the install script generated pages and pages of test messages along the way (mostly all passed), so you'll forgive me if I don't repeat them here.
