OK, I think I've figured out the qt issue.  In a nutshell, it's not an 
issue.  I was checking the version of x11-libs/qt which is what reported 
only 3.3.8 being installed.  But when I look for all qt-* packages I 
find that version 4.5 of them are installed.  So not understanding why 
there apparently wasn't a dependency on x11-libs/qt, I went ahead and 
emerged it.  The merge note said that this was a meta package that was 
going away in the future.  Light bulb illuminates.  The qt4 USE flag was 
pulling in the qt-*:4 packages, just not the meta package.

Thank you,
