Same issue here, except that instead of OSError: [Errno 86] Bad CPU type in executable I get OSError: [Errno 8] Exec format error, which seems a more generic version of the same error (I guess due to python 3.8 vs 3.9).

fontcustom 2.0.0 ruby 2.7-1.4 Python 3.8.9 OpenSuse Tumbleweed, kernel 5.11.15-1-default, arch x86_64

Trying to execute the bundled executable directly confirms it’s the wrong exec format bash: /.../ruby/2.7.0/gems/fontcustom-2.0.0/lib/fontcustom/scripts/sfnt2woff: cannot execute binary file: Exec format error

I fixed it by building and installing on $PATH the sfnt2woff and woff2sfnt binaries from wget/sfnt2woff.

Maybe @kleibert has a non-standard architecture for macOS ? That could require shipping several different executables to cover mac installs
In any case, I suggest writing a better error message for when the fallback sfnt2woff generates a FileNotFoundError, and maybe adding sfnt2woff to the dependencies in the installing instructions.

In my case, upgrading Ruby resolved the issue:

brew upgrade ruby

Afterward, I updated the path and set some necessary flags/variables in ~/.zshrc:

export PATH=/opt/homebrew/opt/ruby/bin:$PATH
export LDFLAGS="-L/opt/homebrew/opt/ruby/lib"
export CPPFLAGS="-I/opt/homebrew/opt/ruby/include"
export PKG_CONFIG_PATH="/opt/homebrew/opt/ruby/lib/pkgconfig"

Then, I restarted the zsh shell to ensure the changes took effect:

zsh -l

These steps effectively resolved the problem for me.
