How to install kcachegrind / qcachegrind on Mac OSX

Computer setup

cachegrind, install, Mac, OS X, profiling

Installing kcachegrind via macports takes a long time because it has to build KDE, as well. An alternative faster way is described below.
* download Qt binary and install it
* download and install graphviz; I used brew install graphviz
* fix default graphviz location by symlinking to a place where cachegrind will find it sudo ln -s /usr/local/bin/dot /usr/bin/dot
* qmake -spec 'macx-g++'; make
* copy generated to your Applications folder
* enjoy!
