see: https://sourceforge.net/p/freeimage/discussion/36110/thread/605ef8e4/
short version: LibWebP does not compile under c11 which is GCC5+'s default mode.

resolutions:

  1. modify /ext/rfreeimage/extconf.rb, add -std=gnu89 to CFLAGS
    or
  2. patch freeimage/LibWebP source code

simple workaround for rfreeimage users until this issue is resolved:
CFLAGS=-std=gnu89 gem install rfreeimage
