agreed with viktor, using the system provided one is definitely safer

On my MacOS laptop I get:
$ /usr/local/bin/pkg-config --libs libffi -lffi
which does not use the "brew"-installed libffi. Not surprising, since /usr/local/lib/pkgconfig/ has no symlink to the "libffi.pc" file.
When updating "libffi" HomeBrew reports:
==> libffi libffi is keg-only, which means it was not symlinked into /usr/local, because macOS already provides this software and installing another version in parallel can cause all kinds of trouble.
For compilers to find libffi you may need to set: export LDFLAGS="-L/usr/local/opt/libffi/lib" export CPPFLAGS="-I/usr/local/opt/libffi/include"
If the MacOS libffi works, it is probably safer to use it rather than the HomeBrew version.
