Summary: pip install pyobjc fails

Initial Comment:
I have installed a new version of Python (2.7) on my Mac using brew, and successfully installed a number of packages thereafter using pip. I am trying to get matplotlib up and running, and it needs PyObjC for the rendering backend. However, when I try "pip install pyobjc" it fails with a traceback when trying to install pyobjc-core :

Downloading/unpacking pyobjc-core==2.3 (from PyObjC)
  Running setup.py egg_info for package pyobjc-core
    Traceback (most recent call last):
      File "<string>", line 14, in <module>
      File "/usr/local/var/pip/build/pyobjc-core/setup.py", line 452, in <module>
        **extra_args
      File "/usr/local/Cellar/python/2.7.1/lib/python2.7/distutils/core.py", line 152, in setup
        dist.run_commands()
      File "/usr/local/Cellar/python/2.7.1/lib/python2.7/distutils/dist.py", line 953, in run_commands
        self.run_command(cmd)
      File "/usr/local/Cellar/python/2.7.1/lib/python2.7/distutils/dist.py", line 972, in run_command
        cmd_obj.run()
      File "/usr/local/var/pip/build/pyobjc-core/setup.py", line 110, in run
        orig_egg_info.egg_info.run(self)
      File "<string>", line 7, in replacement_run
    AttributeError: class egg_info has no attribute 'iter_entry_points'

I've tried peeking at the setup.py file in pyobjc-core, and it seems to do some confusing things like importing a module and using it as a superclass (?). At any rate, frustrating. Any help on this would be much appreciated ! I'm happy to provide more info, too, if it helps pin down what's going on here.
