Error: SPACK_FC in spack setup #9395
Description
While trying to run spack setup, I get an error that seems to be due to SPACK_FC being undefined. Note that none of my software stack is written in Fortran. I'm on a Mac with no Fortran compiler.
Steps to reproduce the issue
$ spack -sd setup omega-h@localError Message
