Ok, so in order to do this, I need to install the version in the trunk. I hate to say it, but that's causing me trouble as well... $ sudo easy_install pyobjc==2.2b1 Searching for pyobjc==2.2b1 ... Running pyobjc-2.2b1/setup.py -q bdist_egg --dist-dir /tmp/easy_install-_86MCZ/pyobjc-2.2b1/egg-dist-tmp-Q8jX-H The required version of setuptools (>=0.6c9) is not available, and can't be installed while this script is running. Please install a more recent version first, using 'easy_install -U setuptools'. (Currently using setuptools 0.6c7 (/System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python)) error: Setup script exited with 2 $ sudo easy_install -U setuptools Searching for setuptools Reading http://pypi.python.org/simple/setuptools/ Best match: setuptools 0.6c9 Processing setuptools-0.6c9-py2.5.egg setuptools 0.6c9 is already the active version in easy-install.pth Installing easy_install script to /usr/local/bin Installing easy_install-2.5 script to /usr/local/bin Using /Library/Python/2.5/site-packages/setuptools-0.6c9-py2.5.egg Processing dependencies for setuptools Finished processing dependencies for setuptools $ sudo easy_install pyobjc==2.2b1 (Same as first try) Is there some config file that will allow me to get this to point to the right setuptools?
