Continuing with insight3d...

...Seems like my opencv was built for i386 architecture (despite being on a 64 bit architecture).
Manually changed CMakeCache.txt to read:

CMAKE_OSX_ARCHITECTURES:STRING=x86_64

did make clean and make, we'll see how it goes (takes a long time to compile, IIRC).

Didn't work right away.

Deleted contents of build dir, and rebuilding, using instructions at http://opencv.willowgarage.com/wiki/Mac_OS_X_OpenCV_Port, but also changing architecture to x86_64.

Getting trouble with carbon, because it is not 64 bits. Trying to disable carbon.
Uncommented #undef HAVE_CARBON something in cvconfig.h
That didn't work.

Modified the CMakefile for highgui to use gtk+ highgui code also under APPLE.
rebuilding (in src/highgui/CMakeLists.txt). This time it actually built.

Argh. Now I get the following when building insight3d:

This mix of 64 bit and 32 bit libraries is really frustrating. I imagine some will be 32 bit, others 64 bit. What is the best strategy? Force everything to be 32 bits? 64 bits?

The night ends in frustration.
