The argument you are making seems to be that all you can find are small parts of a solution, rather than the whole solution itself, you want a spaceship and all you can find are wheels. If that's the case you are probably looking in the wrong place, there are plenty of complete solutions out there for many different problems, just most of them aren't on CPAN because CPAN is more about modules than applications. To use your spaceship analogy, CPAN isn't the shipyard, CPAN is the tool shed at the shipyard.
