Re: gfortran for M1?

Thank you Marius,

it did not help. I also reboot the machine.
Now I am getting:

ld: library not found for -lm
collect2: error: ld returned 1 exit status

I am not sure whether the message from collect2 was there before running 
sudo port select gcc mp-gcc-devel.

I am using bash, but in default zsh it behaves the same.
