Handle systems with pkg_resources but without setuptools (I am looking at you Ubuntu.. grrr). Fixes LP#410528

move the new bootstrap aside to let virtualenv users that have packages linked to bootstrap in trunk stay happy.

merge lp:~gary/zc.buildout/python-support (also available as svn+ssh://svn.zope.org/repos/main/zc.buildout/branches/gary-launchpad).  This adds support for system Pythons, as well as other changes, such as improved Distribute support and some cleanups.

Warning when a script name passed in 'scripts' argument of easy_install.scripts
is not defined in an entry point.

fixes for bootstrap and a system Python; changes based on learning what would be necessary to be able to develop buildout with a system Python (zc.recipe.testing would also need to use sitepackage_safe_scripts)

both from command line and from config files.

and avoid spurious test failures.

fail. The change had to do with the way setuptools was installed.
This seems to explain the changed test output, which is incidental to
what's tested. This test *was* only run for Python 2.5.

I've changed the test to run whenever Python 2.4 isn't used and
updated the test to reflect the new output.

Lots of good cleanup changes, including making windows tests a bit
more robust.

with these changes, I can build zc.buildout and run its tests successfully with my system Python.  To make it fully robust, zc.recipe.test probably would need to use sitepackage_safe_scripts, but this works for now.
