[Pythonmac-SIG] pkg_resources and Mac OS X compatibility

[Bob Ippolito]

With the way that we're returning the distutils platform on the universal branch of Mac OS X, we need another patch to pkg_resources. The reason for this is that distutils.util.get_platform() returns the platform that it is trying to produce binaries for, which is often not the exact current platform. More specifically, our current strategy is to produce a version of Python that will build extensions that are compatible with Mac OS X 10.3, but the actual building of extensions requires Mac OS X 10.4 or later (because the toolchain doesn't exist on Mac OS X 10.3).

In some rare cases, people will want to produce packages that explicitly require Mac OS X 10.4 or later, which they can do by setting the MACOSX_DEPLOYMENT_TARGET=10.4 environment variable when running setup.py. This will influence the value returned by disutils.util.get_platform(), and will influence the compiler and linker if extensions are built. This patch adds an internal _get_max_platform(plat) function that returns the actual runtime version of Mac OS X, for use in compatible_platforms.
