Thanks Dave, appreciate the tip.

I tried replacing 'setuptools' with 'enstaller' in the code and got the
following result:

Retrieved config from: /Users/davidkim/.enstallerrc

Traceback (most recent call last):

AttributeError: 'NoneType' object has no attribute 'location'


It's unclear to me where these files are and how I can get to them. I used
the following bootstrap.py code.

import os, shutil, sys, tempfile, urllib2


> tmpeggs = tempfile.mkdtemp()


> is_jython = sys.platform.startswith('java')


> ez = {}

exec urllib2.urlopen('http://peak.telecommunity.com/dist/ez_setup.py'

                     ).read() in ez

ez['use_setuptools'](to_dir=tmpeggs, download_delay=0)


> import pkg_resources


> if sys.platform == 'win32':

    def quote(c):

        if ' ' in c:

            return '"%s"' % c # work around spawn lamosity on windows

        else:

            return c

else:

    def quote (c):

        return c


> cmd = 'from setuptools.command.easy_install import main; main()'

ws  = pkg_resources.working_set


> if len(sys.argv) > 2 and sys.argv[1] == '--version':

    VERSION = '==%s' % sys.argv[2]

    args = sys.argv[3:] + ['bootstrap']

else:

    VERSION = ''

    args = sys.argv[1:] + ['bootstrap']


> if is_jython:

    import subprocess


>     assert subprocess.Popen([sys.executable] + ['-c', quote(cmd), '-mqNxd',

           quote(tmpeggs), 'zc.buildout' + VERSION],

           env=dict(os.environ,

               PYTHONPATH=


> ws.find(pkg_resources.Requirement.parse('enstaller')).location

               ),

           ).wait() == 0


> else:

    assert os.spawnle(

        os.P_WAIT, sys.executable, quote (sys.executable),

        '-c', quote (cmd), '-mqNxd', quote (tmpeggs), 'zc.buildout' +
> VERSION,

        dict(os.environ,

            PYTHONPATH=

            ws.find(pkg_resources.Requirement.parse('enstaller')).location

            ),

        ) == 0


> ws.add_entry(tmpeggs)

ws.require('zc.buildout' + VERSION)

import zc.buildout.buildout

zc.buildout.buildout.main(args)

shutil.rmtree(tmpeggs)


Apologies in advance if I'm being dense. Thanks so much for the help.
