homebrew opencv now defaults to opencv2. For those visiting here, the following works at the time of writing:

brew install opencv@2
gem install ruby-opencv -- --with-opencv-lib=/usr/local/Cellar/opencv@2/2.4.13.5/lib \
                                             --with-opencv-include=/usr/local/Cellar/opencv@2/2.4.13.5/include/

There seems to be issuing installing the ruby-opencv with ruby 2.6.2. Installing on 2.5.3 seemed to work fine. Cheers
