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.
