Comment(by balazs.vagvolgyi@…):

 The issue seems to be an interference with the default `MIN(a,b)` macro in
 one of the OS X frameworks.

 Got it working by modifying the following files:

 OpenCV-2.2.0/modules/core/include/opencv2/core/core.hpp
 OpenCV-2.2.0/modules/core/include/opencv2/core/operations.hpp

 The modification involved creating another `MIN` macro in both files, I
 called it `__MIN(a,b)`:

 `#define __MIN(a,b) ((a)<(b)?(a):(b))`

 and replacing all `MIN(...)` calls with `__MIN(...)`.

 After the changes opencv compiles without errors.
