Indeed it does.  This is good news.

The only dilemma I'm having is that for the stock Qt 4.2.2 .dmg  
framework, QtUiTools gets installed as a normal library in /usr/lib  
even though the rest are frameworks.  This isn't a big deal, except  
that FindQt4 uses NO_DEFAULT_PATH when looking, so it doesn't see it  
there.
