The idea is that is should allow for better testing, and possibly a more sensible interface.
For some reason, Module::Build(0.38) didn't like the syntax I used to define the repository (I liked that syntax because it should have allowed me to define the repositry in a very detailed manner).
To try to explain what is going on with the intermittant CPAN test failures
It was redundant, and the portability test was complaining about it.
