Distutils doesn't directly support binary distribution, and thus
requires yet another complex set of dependencies: properly configured
compiler(s), and potentially C libraries. Not to mention the fact that
it doesn't support dependencies at all to begin with, even between
Python things. Also, anything distutils/PyPI based would probably be
the burden of package authors/maintainers, not of platform gurus, so
it's much less likely to actually work properly (at least on our
I would also imagine that it was also done this way because Jack could
sneak it by and nobody would try and bog him down with a massively
cross-platform metadata heavy PEP-backed implementation.
