if tried make manually tutorial http://tilomitra.com/opencv-on-mac-osx/ see error after make -j8

i have encountered similar problem building opencv using brew. central issue opencv not build when building against ffmpeg (it try if ffmpeg installed.)

as suggested here, problem can resolved using following brew command build opencv, forces alternative version of build environment (one of top troubleshooting suggestions brew):

brew install opencv --env=std

hope works too!
