# This script is known to work on:
# OS X 10.5.8, Xcode 3.1.2, SDK 10.5, MacPorts 2.3.3
# OS X 10.9.5, Xcode 5.1.1, SDK 10.9, MacPorts 2.3.2
# OS X 10.10.3, XCode 6.3.2, SDK 10.10, Homebrew 0.9.5/8da6986
#
# You may need to set PATH to include the location of your
# PackageMaker binary, if your system is old enough to need that.
# Setting MACOSX_DEPLOYMENT_TARGET will select an SDK as usual.
#
# If you are using Homebrew, you should install protobuf (and any
# other future Homebrew dependencies) with
# `--universal --build-bottle`.
# The first option should be fairly obvious; the second has the side
# effect of disabling Homebrew's overzealous processor optimization
# with (effectively) `-march=native`.
