First, when installing fpm it seem the install.sh has some problems:

If reporting this issue please do so at (not Homebrew/brew or Homebrew/homebrew-core):

These open issues may also help:
Documentation: Please add fpm version update instructions to the README.md https://github.com/fortran-lang/homebrew-fortran/issues/18

Second, when installing lfortran the llvm@11 is disabled:

❯ brew install lfortran
==> Fetching dependencies for fortran-lang/fortran/lfortran: llvm@11 and zlib
Error: llvm@11 has been disabled because it is a versioned formula!

On MacOS 14.1.1 (Arm64), brew 4.3.9

I have solve the fpm via the pip3 with pip3 install fpm

Humm, the pip3 workaround appears broken as well

pip3 install fpm
