Did you try with the very last revision (hg:d6719412b9a3)? There were some little changes with AMC-detect.cc

I'm trying to build it through MacPorts, so how do I get the latest development version from there?

Cloned the repository and tried to build it and it also fails...

... and after installing dblatex using MacPorts it still won't build...

You can skip reproducible-pdf.pl without too much damage, adding a line

exit 0;

Or use

AMCCONF=macports make

Nope, still not building...

OK, with OpenCV3, you need something else…
You can try

AMCCONF=macports GCC_OPENCV_LIBS=" -lopencv_core -lopencv_imgproc -lopencv_imgcodecs " make

But I'm not the right one to help you with OSX… maybe you can find some hints in the related French threads: OSX Sierra, [MacOS] erreur à la compilation de mac-devel , Installation de la version de développement d'AMC sous OS X Mountain Lion.

Hi,

Installation of last version of AMC on macOS 10.12.1 works now. The opencv port was updated on MacPorts and there is no need to try another type of installation, MacPorts does the job. The installation still need an adapted version of GCC5 and pdftk that provoke a long, a very long installation. But once installed all works.

Installation pages on the wiki where updated.
