[petsc-dev] Gfortran Fix for "library not found for -lSystem" macOS Big Sur

[Jacob Faibussowitsch]

Follow up, seems that things are more borked than I previously thought. Adding the below to $LIBRARY_PATH makes gfortran work, but MPICH build now fails with:

ld: framework not found OpenCL
collect2: error: ld returned 1 exit status

(Along with 10 different unsigned to signed conversion warnings).

Best regards,
