Describe the bug

1. List the steps someone needs to take to reproduce the bug.
   Build dart on a machine such as Perlmutter, where the recommended compiler wrapper is ftn.
   FC = ftn
   Or in EMSFx containers where the compiler is gfortran-version
2. What was the expected outcome?
   You can build DART
3. What actually happened?
   DART fails to build

You can set FC = gfortran

MPIFC = ftn
MPILD = ftn
FC = gfortran
LD = ftn

but then you loose the compiler wrapper functionality (e.g. linking to netcdf, whatever else they have set up on the machine).

Which model(s) are you working with?

ESM3, lorenz_96, all models.

Version of DART

Which version of DART are you using?
You can find the version using git describe --tags
v11.10.9

Have you modified the DART code?

No
