Port auto-multiple-choice not installing

[chfarges]

Hello, I managed to install all dependencies related to the port auto-multiple-choice but the port itself does not install. I am on OSX Sierra. It appears to be related to opencv (opencv is installed). Here is the relevant part of the log :

:info:build /opt/local/include/opencv/highgui.h:46:10: fatal error: 'opencv2/highgui/highgui_c.h' file not found :info:build #include "opencv2/highgui/highgui_c.h" :info:build ^{:info:build 1 error generated. :info:build make: * [AMC-detect] Error 1}
