Compiling Issue on Mac (OS Monterrey, M2 processor)

Hi,

After git cloning https://github.com/Michalychforever/CLASS-PT.git (git pull results in

From https://github.com/Michalychforever/CLASS-PT

• branch HEAD -> FETCH_HEAD
  Already up to date.

Otherwise, it says "no .git repository" without "git clone"), and changing the path to where I have OpenBLAS installed ("/opt/homebrew/opt/openblas/lib/libopenblas.a"), typing "make clean; make" results in the following error:

To see if it's a gcc/gfortran compiling issue, I tries compiling simple scripts in both C and Fortran, and they both compiled (in screenshot for reference), so I don't think it's a M2 gcc compiler issue as previously thought.
Is there a way to fix this?
Thank you so much for any help/
