I know that a few ports try to be smart and check a bit more then others but the problem is that checking for each and every combination of options for all dependencies does not scale. In big ports you end up with a big mess. Many projects have their configure to check specific features and version ranges of their requirements which usually gives you a good idea of what is wrong but vbox doesnt. So if someone wants to improve that send a patch for vbox configure to check for python threads.
