Comment (by dyne2meter):

 I don't recommend even thinking about porting SageMath. I had to install
 some basic stuff in Homebrew just to have the necessary build system. The
 SageMath config file hiccups as soon as it detects /opt/local/macports,
 not because the necessary components are there, but because too much
 Python stuff is there, I think. I needed a gcc10, which macports has, but
 so it goes. Now I have two installations of gcc10. Let's not even talk
 about what installing Julia duplicates, or threatens to if you are not
 careful.

 The world of OSS math stuff is a free-for-all. No pun intended.

 My build of SageMath failed without Homebrew gcc10, because something in
 building NumPy did not work correctly. I think it would be great to see
 SageMath supported at MP. Maybe just tweaking the config file might work,
 but the source repo does not include a config. You have to issue "make
 config" first. I'm thinking, this will be hairy to port.
