The option or the LC_VERSION_MIN_MACOSX value? I'm running OSX 10.8, where both are available, but according to Google LC_VERSION_MIN_MACOSX was introduced in a 10.6 subrelease. Without that load command you cannot easily see what the deployment target is (the best way I find while writing would be a tool that checks library load commands and the list of symbols used with a to-be-maintained registry). > >> Both can also be found using macholib ;-) > > probably best not to add another dependency. > > But I've lot track on why we'd need this -- presumably the wheel > builder would know what it built, and could supply the proper > meta-data, and that would be that. You don't need this, distutils (and hence setuptools) already knows this information and other build tools can also know this.
