Please don't use "setuptools", the "rotten .egg" install system.

     I can do it, I just have better things to do than system
administration.  The fact that Python doesn't "just work" is
part of why it's losing market share.

     If it can be built with "python setup.py build", go that way.
A "setup.py" script, invoked with the correct Python, reliably
knows which Python it is supposed to update.  "egg" files
usually have trouble with that.

     Prebuilt systems should use the installer for the distro, and
work with yum, apt-get, or the Windows installer as appropriate.

     It does seem to be necessary to install the development tools
on a Linux system just to get various Python packages to install.
Major packages are still all over the place.
PyPy is just a directory of links, not a repository like CPAN.

     Python sort of slips through the cracks.  Nobody is doing
the work to make PyPy handle these problems, and Python isn't
important enough for MySQL, etc. to support the connector for
the language.  (They support Perl, C, Java, etc., but not
Python.)
