First of all, yes the presented solution was somewhat complex, partly because it is still a proposed idea and definitely up for optimizations. However I am still very convinced of my approach, something I should discuss in more detail.

He mentions some of the downfalls that PHP applications have had up until now as far as ease of deployment and the maintaining of dependencies. Most of the suggested solutions aren't optimal, so a system using the PEAR installer would have to overcome some of them and keep it simple to use. Benjamin has taken the PEAR installer and laid his new Pearanha tool on top of it to help you create custom PEAR installer scripts.
