apt and aptitude are not the same program and have very different

behavior even through they share a 3 letter prefix and a library in
various areas, so don't assume that what I am saying about the
resolver in libapt which apt-get is using has anything to do with aptitude
which has its own or the various other libapt front-ends which might or
might not use the solver, or use it differently.
(Ignoring that most of them could use an external solver)

that the order changed "recently" (Nov 2011). A certain individual – who
I am not going to call out in public to protect him from the lynch-mob –
made the mistake of changing the code to sort lowest priority first …

This is indeed the recommend solution if you have a default as nowhere is

defined which provider of a priority is chosen. While priority might be an
obvious and easy choice for solvers working with a heuristic, I wouldn't be
surprised if more deterministic solvers would go for the least 'changes'
instead which might not be an optimal "default" choice.
Maybe you want to try it with: apt-get install $whatever --solver $solver
[where $solver is likely "aspcud" as we haven't that much more so far]
Also: build-dependencies, but that is probably not an issue for PHP.
