What about SAGE, MPL, PyTables, and friends? I don't really know what all
depends on Numpy at this point, but I think Ron's point about Windows
packages is a good one. On Linux I just compile all these from svn anyway,
but I suspect windows users mostly depend on precompiled packages. And this
probably also effects packagers for Linux binary distros like ubuntu and
fedora also, as they have to recompile all those packages and keep the
dependencies straight. True, most of the packages trail numpy development by
some time, but that is also an arguement against the urge to push things in
