Very nice. Just a piece of unsolicited advice :)

Instead of tracking the master branch of all of these repositories, you should grab specific tags/commits. This reduces the chances that you'll end up with a bug in your stack that is impossible to track down because it could be coming from project X, Y, or Z.

Also, you should check out hashstack, we can handle a reproducible, versioned install profile like this in a similar amount of code (or less). I haven't put together an isolated SciPy stack, yet, but I'd be happy to do so if it would be useful.
