Error installing CrackMapExec

[cpt-kernel]

It looks like the installer is unable to locate 'ffi.h', a libffi file. I've ensured that libffi is installed. I have python3, cffi, and relevant dependencies installed and PATH'd.

I've run:
export PKG_CONFIG_PATH="/usr/local/opt/libffi/lib/pkgconfig"
and
export LDFLAGS="-L/usr/local/opt/libffi/lib"

Output of error:
