Don't take what I am saying here as a recommendation, but, I know that ActiveState provides a service called
PerlDirect which attempts to address some of these issues. From what I have heard, they do QA on Perl as well as popular modules and bundle them into a special, periodic distribution that is aimed at large corporations.
I have recommended that this service be evaluated by one of my corporate clients, because they give integration testing tasks to people from a "UNIX Core Group" which knows a great deal more about the core of the Solaris operating system than it does Perl. In situations like the one I am describing, it is often up to the individual development teams to perform extensive unit testing on their finished products because the IT department only certifies the modules that are distributed with Perl itself. Needless to say, this is not an optimal solution.
