Worst this happens when installing the SSL module also.

We have endured thisssl pain in our collective ass since the origin of times, and this will subside until OpenSSL receives a GPL-compatible license. Since it is not yet the case, we cannot distribute OpenSSL with Sage source or in precompiled packages (some precompiled packages depending on, but not containing, OpenSSL are available for various Linux distributions).

When compiling Sage by yourself, it is enough to install OpenSSL (and its development packages). I amnot aware of the solution to use to enable it in precompiled packages/distribution ; furthermore, I am aware that Apple's shenanigans with Xcode complicate the problem even further.

Could you forward your question to sage-support ?

Is there no way to make pip work with NSS instead?

If installing from binaries, once installed, fix using

If compiling from source, try installing as many things as possible from Homebrew.

In particular, OpenSSL, and ideally Python too (currently Python 3.8 works best).

$ brew install openssl python@3.8
$ cd <path_to_sage_directory>
$ git pull origin master --tags -q  # replace master by develop if adventurous
$ source .homebrew-build-env
$ make configure
$ ./configure
$ make -s V=0

Or try installing with Conda. See:
