I need to sign off for the night, but the numpy error is definitely related 
to gfortran.  If you have gcc installed via homebrew then it should come 
with the latest version of gfortran.  You can see from your config.log file 
that gfortran is not found:

configure:7281: checking for gfortran
configure:7311: result: no

and other standard homebrew packages are not found, like openblas:

configure:12171: checking BLAS library
configure:12190: result: openblas
configure:12239: checking whether any of gfortran is installed as or will 
be installed as SPKG
configure:12243: result: yes; install openblas as well
configure:13540: no suitable system package found for SPKG openblas

are you aware if you have gcc and openblas installed via homebrew? I also 
see that you didn't run "source .homebrew-build-env" before running 
./configure since I don't see certain items on your path.  If you go to the 
sage installation guide 
at 
https://doc.sagemath.org/html/en/installation/source.html#macos-recommended-installation
 
you can see a list of homebrew packages you might want to have before 
installing sage.  I think if you get everything in working order with 
homebrew then you shouldn't have any issues installing sage.  Here is my 
best suggestion as to what to try:

- fix all "brew doctor" warnings.  This might not be necessary, but I get 
worried when I see so many warnings.  You can probably just delete all the 
suggested files and you should be fine.

- install all the recommended homebrew packages.  If any are already 
installed then maybe try "brew reinstall" to make sure it is installed 
properly.  If you think you have homebrew gcc installed then you should be 
able to do "which gfortran" and "gfortran --version".  That should 
hopefully show you that you have gfortran 10.2.0_3.

- in your sage folder under the develop branch you should run the commands 
I mentioned, and don't skip out on "source .homebrew-build-env":

>> make distclean
>> ./bootstrap
>> source .homebrew-build-env
>> ./configure

Before running "make -j4 build" you can look at config.log and make sure 
that it picked up all of the relevant homebrew packages.
