There exists within Perl the ability to support such a development and deployment framework. I know, I built one for a Fortune 1000 (620's). It requires dedication to the process and framework, and most important of all, a toolmaster. The easy part is the coding standards surrounding use of the framework to implement override libraries. Then, your applications deploy with whatever versions of libraries you want to use. You can even tier the libraries for enterprise, platform (e.g. dev/stg/prd), and project. Regardless of the complexity of the framework, it must be trivially easy to embed within your applications. Otherwise, your programmers will find the path of least resistance, and following your framework won't be it. I'd be glad to post some code if desired.
