I guess some package management would be an improvement from the present situation. the fact it only works for python packages is a bit half baked but it is a good step in my opinion.
As far as I can tell this means that once we have bootstrapped pip we can simplify spkg-install for python package by just calling pip. One very interesting question has been raised: how does it deal with patching and other custom settings that are used in what I will call "vanilla" sage (as opposed to lmonade or sage-on-gentoo). We definitely want a way to include patches or special pre-build steps in. The easy upgrade will lead you in interesting territories too. In my sage-on-gentoo install I currently use numpy-1.8.1 scipy-0.13.3 rpy 2.3.10 for example. I am not currently suggesting vanilla to move to numpy-1.8.x currently because scipy has to drop "import old numeric" statement that trigger a bunch of extra doctests warnings that are not in vanilla. You'll have to be ready for things to break if you upgrade cython early, ipython also comes to mind. It will ease some experimentation but we have to be able to settle on a given version for each package in the default build. I assume it is the case that you ask pip for a specific version.
