PB installation compass

Default
,

Bonjour,
je suis sous mac osX el capitan.
J'utilise depuis peu sass et grunt pour mon intégration web. c'est grunt qui gère la compilation de mes .scss en .css.

Je souhaite me rajouter la couche compass pour profiter des mixins,etc...

PROBLEME :
je n'arrive pas à installer compass depuis mon terminal
je fais la commande "sudo gem install compass" (j'ai également fait la maj de ruby avant avec "sudo gem update --system")`
il me sort l'erreur suivante :

"
MBP-de-LE:~ macfabien$ sudo gem install compass
Building native extensions. This could take a while...
ERROR: Error installing compass:

To see why this extension failed to compile, please check the mkmf.log which can be found here:

/Library/Ruby/Gems/2.0.0/extensions/universal-darwin-15/2.0.0/ffi-1.9.10/mkmf.log

extconf failed, exit code 1

Gem files will remain installed in /Library/Ruby/Gems/2.0.0/gems/ffi-1.9.10 for inspection.

quelqu'un aurait il une solution ?

Je sais que je te réponds à côté mais utilise node-sass et autoprefixer, tu pourras totalement te passer de compass (qui te force à utiliser ruby)
