Treeripper

I get an error "dyld: Library not loaded: /usr/local/lib/libMagick++.4.dylib" on MacOS X

The problem lies in the architecture:i386 versus x86_64 and the delegate libraries for ImageMagick? need to have the right architecture.

This is a problem related to the different architectures under which libMagick++ and treeripper have been compiled. You need to compile libtiff, freetype, libpng, jpeg, zlib from source. You can find most of these, here: http://www.imagemagick.org/download/delegates/ Then compile ImageMagick? from source on you particular OS and then recompile TreeRipper and this should solve the problem.

I get an "image not found" error

This is a related issue to the previous problem, make sure you have installed freetype and libtiff from source for your computer's architecture
