pyobjc installation failure: xcode-select: error: tool 'xcodebuild' requires Xcode

Question

I need pyobcj in order to have pyttsx work. When I attempt to install pyobjc with pip, I get the following:

My-MacBook-Pro:WebForm $MyName$ sudo pip install pyobjc
The directory '/Users/$MyName/Library/Caches/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.
You are using pip version 7.0.1, however version 7.0.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /private/tmp/pip-build-4NP01v/pyobjc-core

I've retried using the suggested -H flag, with no luck. What am I missing here?

• Python: 2.7.10
• OS: X, Yosemite

XCode is a requirement, so install it and the Command Lines Tools via your preferred shell:

xcode-select --install
