> What do these do. Why are they adding an alternative gettime implementation for MacOS? Why are they patching a bunch of test files to make them pass? The gettime patch is to support macOS SDK < 10.12, as it says in the patch itself. From a quick look, some of the test patches appear to be for Python 2 compatibility. Every linux distribution and system integrator has a patch list just like that for complicated software. If a particular patch concerns you, I would suggest opening an issue on their bug tracker to ask for an explanation. > It's unfortunately one we ran into recently while migrating a legacy system off conda, but it's not the first and I doubt it will be the last. Unclear what that has to do with conda. The same package is available on PyPI (source only), and the line you highlighted almost certainly exists for some other build target than conda, where the compilers will automatically find numpy includes in CONDA_PREFIX without any extra effort.
