As I installed I noticed that a fair bit of time is spent compiling PHP.
Given that PHP5.5 was released so soon after PHP5.4 it seems likely that people on PHP5.3 will jump right to PHP5.5. Or perhaps people just don't care about PHP5.3 any more but do need PHP5.4 or PHP5.5. Whatever the scenario, it seems useful to make it optional to install the different versions of PHP.
