The relative difficulty in building NumPy and SciPy makes me wonder whether people on these 2.4 platforms are even building from more recent tarballs, nevermind SVN.

Building numpy and scipy is difficult, but it is nothing compared to
having to build pygtk/pyqt, etc... which is necessary if you build
your own python.

A lot of clusters and co run on RHEL/Centos, for example. Building
numpy/scipy by yourself is doable, a whole python toolset not so much.

They are ancient IIRC - when I worked in a company which used RHEL, it
was useless, I compiled atlas/numpy/scipy by myself.

Knowing how many people depend on python 2.4 support is not possible,
so we are a bit in the dark. But again, as mentioned by Pauli already,
supporting 2.4 instead of 2.5 is not that difficult - the cost is
really low. And as a data point, a lot of heavily used libraries also
support python 2.4.
