Missing wheels for M1 macs, does not compile on macOS 13.4

[chbndrhnns]

I tried to install mkdocs-exporter which depends on this library. It seems there are no wheels (I am on Python 3.11 and a M1 mac) and pip install libsass fails with such an error.

The stacktrace is so long that I am uploading it here as a file.

log.txt

Is there anything you could do to help?

oldest M1 I have on hand is 14.x -- so you'll have to upgrade to get a prebuilt but I've just uploaded one

Thanks, works great!

I'm on an M1 macbook pro with macOC 14.2.1 and it's not building for me, any idea?
