Freetrack is a bit outdated, there are alternatives which don't need a patch/fix if you want to use a ps3-eye.
opentrack
https://github.com/opentrack/opentrack/releases
Facetracknoir
http://www.facetracknoir.nl/
Both of them are still updated and get more features added.
And something instead of ir-tracking:
