Hello, 

I was able to get sage to build (I had to do a lot of switching back and forth of the CXXFLAGS and LDFLAGS to my MacPorts installation. I encountered another error though I can't seem to get past and that is in relation to sage-doc-html.

[sagemath_doc_html-none] [spkg-install] /sage-develop/local/var/lib/sage/venv-python3.9/lib/python3.9/site-packages/urllib3/__init__.py:34: NotOpenSSLWarning: urllib3 v2 only supports OpenSSL 1.1.1+, currently the 'ssl' module is compiled with 'LibreSSL 2.8.3'. See: https://github.com/urllib3/urllib3/issues/3020

Is there a version that is easier to build than the beta or a prebuilt version that allows packages to be installed?

[Dima Pasechnik]

Hello,

you might have better luck using a prebuilt python, e.g. the one supplied by python.org
At least this would avoid all these ssl shenanigans.

Hi Mavin.

Just in case, I encountered this problem too on macOS, but with Homebrew.

For ./configure to pick Homebrew Python (instead of /usr/bin/python3, giving "NotOpenSSLWarning") I had to
brew install python-setuptools
