Did you check if the programs in question really do depend only on Qt4? 
  Try the ldd tool to see the libs a binary uses.

I do have "-qt4" in the USE flags though.  Try that and see how many 
packages this would rebuild (emerge -pDN world).  Yeah, this is pretty 
much shotgun debugging, but it might point to the culprit :P
