Erreur lors de l'installation Homebrew de ffmpeg - avec toutes les options

Après avoir installé ffmpeg en utilisant Homebrew sur mon Macbook Air i7 de fin 2012 avec MacOS 10.12.3, j'obtiens ce message :

Error: File exists - /usr/local/opt/ffmpeg/.brew

Ce chemin est un lien vers /usr/local/Cellar/ffmpeg/3.2.2/.brew qui ls -al se révèle contenir uniquement le fichier Ruby, "ffmpeg.rb"

Auparavant, j'avais installé ffmpeg avec succès en utilisant brew install ffmpeg mais l'a ensuite désinstallé pour le réinstaller avec toutes les options par brew options ffmpeg :

brew install ffmpeg --with-chromaprint --with-fdk-aac --with-fontconfig --with-freetype --with-frei0r --with-game-music-emu --with-libass --with-libbluray --with-libbs2b --with-libcaca --with-libebur128 --with-libgsm --with-libmodplug --with-libsoxr --with-libssh --with-libvidstab --with-libvorbis --with-libvpx --with-opencore-amr --with-openh264 --with-openjpeg --with-openssl --with-opus --with-rtmpdump --with-rubberband --with-schroedinger --with-sdl2 --with-snappy --with-speex --with-tesseract --with-theora --with-tools --with-two-lame --with-wavpack --with-webp --with-x265 --with-xz --with-zeromq --with-zimg

Maintenant, au lieu d'un message de fin d'installation réussie, j'obtiens ceci :

...
==> make install
==> make alltools
Error: File exists - /usr/local/opt/ffmpeg/.brew

Avec brew uninstall ffmpeg J'ai supprimé le /usr/local/opt/ffmpeg/ et le répertoire réel /usr/local/Cellar/ffmpeg/ répertoire. J'ai réessayé l'installation mais j'obtiens la même erreur. A noter que ffmpeg semble avoir été installé avec succès :

Il convient de noter que j'ai utilisé brew prune , brew update , brew upgrade , brew cleanup , brew doctor et

$  brew -v
Homebrew 1.1.8
Homebrew/homebrew-core (git revision 35fb; last commit 2017-01-29)

Il convient également de noter que le message d'erreur apparaît alors que l'installation est en cours. ==> make alltools Je remarque que dans la phase /usr/local/opt/ffmpeg/.brew/ffmpeg.rb le code suivant :

class Ffmpeg < Formula
...
  def install
...
    if build.with? "tools"
      system "make", "alltools"
      bin.install Dir["tools/*"].select { |f| File.executable? f }
    end
  end
...
end

Je ne sais pas si c'est lié, mais depuis que j'utilise l'application --with-tools peut-être l'option bin.install génère l'erreur ?

Même avec le message d'erreur, l'installation résultante contient ffmpeg, ffprobe, ffserver mais ffplay n'est pas reconnue comme une commande...

Le fichier INSTALL_RECEIPT.json indique qu'aucune des options n'est utilisée :

{"homebrew_version":null,"used_options":[],"unused_options":["--with-fdk-aac","--with-libass","--with-libebur128","--with-libsoxr","--with-libssh","--with-tesseract","--with-libvidstab","--with-opencore-amr","--with-openh264","--with-openjpeg","--with-openssl","--with-rtmpdump","--with-rubberband","--with-schroedinger","--with-sdl2","--with-snappy","--with-tools","--with-webp","--with-x265","--with-xz","--with-zeromq","--with-zimg","--without-lame","--without-qtkit","--without-securetransport","--without-x264","--without-xvid","--with-fontconfig","--with-freetype","--with-frei0r","--with-game-music-emu","--with-libbluray","--with-libbs2b","--with-libcaca","--with-libgsm","--with-libmodplug","--with-libvorbis","--with-libvpx","--with-opus","--with-speex","--with-theora","--with-two-lame","--with-wavpack"],"built_as_bottle":true,"poured_from_bottle":true,"installed_as_dependency":true,"installed_on_request":false,"changed_files":["INSTALL_RECEIPT.json","lib/pkgconfig/libavcodec.pc","lib/pkgconfig/libavdevice.pc","lib/pkgconfig/libavfilter.pc","lib/pkgconfig/libavformat.pc","lib/pkgconfig/libavresample.pc","lib/pkgconfig/libavutil.pc","lib/pkgconfig/libpostproc.pc","lib/pkgconfig/libswresample.pc","lib/pkgconfig/libswscale.pc","share/man/man1/ffmpeg-all.1","share/man/man1/ffmpeg-filters.1","share/man/man1/ffprobe-all.1","share/man/man1/ffserver-all.1","share/man/man1/ffserver.1"],"time":1485728076,"source_modified_time":1480980538,"HEAD":null,"stdlib":null,"compiler":"clang","runtime_dependencies":null,"source":{"path":"/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/ffmpeg.rb","tap":"homebrew/core","spec":"stable","versions":{"stable":"3.2.2","devel":null,"head":"HEAD","version_scheme":0}}}
(extra line for ease of scroll viewing)

Pourquoi ce message d'erreur est-il signalé et que dois-je faire pour que l'installation soit réussie avec toutes les options ?

--------------------------UPDATE
L'utilisation $ brew install ffmpeg --force --with... toutes les options ci-dessus, j'obtiens toujours la même erreur, mais en utilisant :

$  brew unlink ffmpeg && brew link ffmpeg

J'ai dissocié 84 liens symboliques et j'en ai relié 114 (30 autres n'étaient pas liés lors de l'installation). Avec cela, j'ai au moins ffplay et le fichier INSTALL_RECEIPT.json contient des éléments dans la section "used" :

Je suis récemment passé de MacOS 10.12.2 à 10.12.3, mais Homebrew semble également à jour. xcode-select version 2347 .
