Cannot install pyorc on Mac M1

[liiight]

First of all, thank you very much for this amazing package, it's super useful!

I'm afraid I'm unable to install it on MacOS 12.3.1 Apple chip, via python 3.10.4:

source /Users/ocarmi/PycharmProjects/shield/venv/bin/activate
pip install pyorc

  note: This error originates from a subprocess, and is likely not a problem with pip.

As the output shows, no M1 compatible wheel is available (though, there's a chance it will be soon), thus it tries to install it from source. The setup.py's build_ext command automatically downloads and compiles the ORC C++ Core library, but since the last release, a new one has been released (1.7.4) and the old one (1.7.3, which module tries to download) has been moved to a different location. Hence the 404 HTTP error.

The build_ext command has some extra flags (--orc-version and --source-url) that you can use to either change the orc lib version to download or set the new URL for the old library. Pip also has some flags (--install-option and --global-option) that I believe could be used to pass options to setup.py's build_ext, but unfortunately it doesn't seem to work (or at least I failed to use it for this particular purpose).

So you have to download the package's source and run the build_ext with the flags manually:

pip download pyorc
tar xzf pyorc-0.6.0.tar.gz && cd pyorc-0.6.0
python3 setup.py build_ext --orc-version=1.7.4 # Or python3 setup.py build_ext --source-url=https://archive.apache.org/dist/orc/
python3 setup.py install

Thanks, installing from source per your instruction indeed work. Thank for the swift response and solution! I appreciate your hard work on this project!
