Thanks Justin, François and Dima, your comments were helpful. I used to quaranteen brew from my sage builds but I stopped doing this because others managed to compile sage along side homebrew, and even recommended which packages to install, and I was able to do this before macos 10.15. When I ran into problems with catalina I tried using brew to uninstall all of the homebrew packages, but I don't think that I checked to see if the directories in /usr/local were empty, perhaps they weren't.
In any case, after renaming the brew directories in /usr/local (specifically the bin, include, lib and opt directories), I can compile sage again! :) When I have some time I will remove brew completely and then add everything back in slowly and try to isolate and better understand the problem.
