Maybe I've misunderstood some important detail, but how will
their "change" help with anything other than making their
distribution a non-standard Python installation ?
distutils allows for a great deal of flexibility. For some
reason, this does not appear to be known to a larger
audience.
I can only recommend reading Greg's great write-up about the
end-user perspective of installing Python modules:
http://docs.python.org/install/
A little known fact is that distutils can easily be customized
using config files:
http://docs.python.org/install/#distutils-configuration-files
Together with the PYTHONHOME and PYTHONPATH environment
variables setup in your .bashrc, this gives you full flexibility
regarding the Python package setup and permits setting up
private Python installations, parallel Python installations,
Python installations sharing packages, etc. etc.
It really depends a lot on what you want to achieve. There's
no one fits all configuration.
Using a non-standard Python installation as system Python is
certainly not a good approach to solving anything. It only
makes it harder for users having to fight problems arising
out of this.
You have the same problem in other areas as well. A prominent
example being Microsoft's tendency (in the past) to tweak standards
to better meet their requirements.

I lost you there.
