Indeed - but this is the reason that python deployment scripts are not
usable for real production deployment and why we use OS packages for
that. (The same is actually true for autoconf or cmake or whathaveyou...
software build/install doesn't handle deps properly, which is why we
have package management in the first place)

Now, I do _not_ know a good solution for this on OSX other that writing
scripts or requiring use of one of the OSX add-on package managers. But
for the forseeable future I'd argue that trying to get a magical
one-step dev env launcher in the tree that handles all of the possible
client oses is a pipe-dream and a waste of time, because it's
essentially an attempt at creating a simple cross-platform package
management system. :) I think for some of it part of the instructions
are just going to have to be "install this software first"

Just my opinion of course...
