[Distutils] Bootstrap use_setuptools() in ez_setup.py failure

[Pherl Liu]

Hmm, I think it now only delete pkg_resource when
pkg_resrouces.VersionConflict is caught, but the fix should be also delete
pkg_resources when pkg_resources.DistributionNotFound is caught. The code
looks like:

   try:
        pkg_resources.require("setuptools>="+version); return
    except pkg_resources.VersionConflict, e:
        if was_imported:
            print >>sys.stderr, (
            "The required version of setuptools (>=%s) is not available,
and\n"
            "can't be installed while this script is running. Please
install\n"
            " a more recent version first, using 'easy_install -U
setuptools'."
            "\n\n(Currently using %r)"
            ) % (version, e.args[0])
            sys.exit(2)
        else:
            del pkg_resources, sys.modules['pkg_resources']    # reload ok
            return do_download()
    except pkg_resources.DistributionNotFound:
        *del pkg_resources, sys.modules['pkg_resources']*  #  added this
line.
        return do_download()
