I'm using homebrew installing opencv3 on OSX(EI Captain), 

brew install opencv3 --with-contrib --with-python3 --HEAD

and an error occurred:

I do brew edit opencv3, then comment the following line

inreplace buildpath/"3rdparty/ippicv/downloader.cmake",
  "${OPENCV_ICV_PLATFORM}-${OPENCV_ICV_PACKAGE_HASH}",
  "${OPENCV_ICV_PLATFORM}"

then you can reinstall again with --HEAD

The opencv repository has fix some issue also removed file 3rdparty/ippicv/downloader.cmake, so no need to patch it any more. But they didn't issue a new release, so to install --with-contrib, you have to install with --HEAD, but disable the patch of file 3rdparty/ippicv/downloader.cmake
