On OSX 10.6, yes. But there one could choose to use a recent gcc version.

I cannot test on the intermediate OS versions, but on OS X 10.9 the situation is a bit more complicated. Apple's current clang version ("3.4 svn") compiles gmic.cpp fine, without particular memory requirements. However, clang 3.5 displays the almost same behaviour as clang 3.3 on OS X 10.6: taking the form of very high memory pressure that basically brings the machine down to a point where it requires extreme patience to get the focus back to the controlling terminal window in order to ^C the process.

Might it be a good idea to disable the gmic extension when not using a verified clang version?

MacPorts installs GLEW as a simple dylib in /opt/local/lib, FindGLEW.cmake has been modified accordingly. I installed Vc (not in MacPorts) by hand into /opt/local; the modification to FindVc.cmake is possibly redundant. The modification to kis_opengl_canvas2_p.h enables building on systems that do not have the (optional!) GLEW framework.
