Do I seriously need to install Xcode and compile PyObjC as a result of 1.7.6 update?

Question

There must be an easier way.

I get this warning when attempting to start my app today:

/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/tools/devappserver2/file_watcher.py:97:

UserWarning: Detecting source code changes is not supported because your Python version does not include PyObjC (http://pyobjc.sourceforge.net/). Please install PyObjC or, if that is not practical, file a bug at http://code.google.com/p/appengine-devappserver2-experiment/issues/list.

The PyObjC installer only requires Xcode because it requires a compiler. However, you can easily get a compiler without downloading Xcode.

Just click this link, and sign in with your Apple Developer ID, or register for a free Apple Developer Account if you don't already have one. Then search the page for the Command Line Tools, download them, and install them.

Once you have installed the Command Line Tools, you can install PyObjC using the instructions on the website.

The website details how to install using either pip, easy_install, or manually. I will briefly outline the first two methods below (manual installation is slightly more involved, and you should read the instructions on the site.):

pip:

env CC=clang pip install -U pyobjc-core
env CC=clang pip install -U pyobjc

easy_install:

easy_install -U pyobjc-core
easy_install -U pyobjc

manual installation:
