I produced this page recently; FWIW I also came up with the pared-down package 
lists that went into the Quick Start Guide which this page borrows. How is 
this contradictory if it uses the same information?

So I don't recall exactly how perl got on that list; but python and git are 
absolutely required on the host. That's why they're in ASSUME_PROVIDED.

Er, no. Well, if by "handle automatically" you mean "error out when they are 
not present" then that's not very helpful - it's much easier if people just 
get a list of what they need to install up front.
