 {{{
 $ port -v installed libsdl2
 The following ports are currently installed:
   libsdl2 @2.0.6_0 (active) platform='darwin 17' archs='x86_64'
 date='2017-10-08T19:33:48-0700'
 }}}
 Not sure what to say. Make sure your system is fully up to date with all
 the app store updates, make sure you have Xcode 9 and the current command
 line tools installed. Then `sudo port clean libsdl2` and try again.
