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