You have to install development tools first.

Gem files will remain installed in /Library/Ruby/Gems/2.0.0/gems/ffi-1.9.5 for inspection.

解决方案
Actually, this seems to be successfully answered at Installing 'Compass' via the command line receive error "extconf failed, exit code 1"

You evidently need to first install development tools   (xcode-select --install), then install compass

good luck!
