I was surprised to find that /Library/Frameworks/gecode.framework/Versions/ contains a folder named "35" -- I would have expected it to be named "42", for version 4.2, but that could of course be simply a wrong guess on my part.

I tried to better isolate the problem. Both g++ (gcc) 4.2.1 and clang 5.0 report problems with the example send-more-money.cpp (http://www.gecode.org/doc/4.2.0/MPG/send-more-money.cpp), but the errors differ. The details are below. 

What am I missing?  

Best wishes,
