It would probably be easiest just to create three lists as follows:

moc-qt5 uic-qt5 rcc lrelease-qt5

moc-qt4 uic-qt4 rcc lrelease-qt4

moc uic rcc lrelease

and checking if the first group is all present, if not then the check if 
the second group is all present, if not then check if the third group is 
all present.  If one desired, that could be placed within a second loop 
and instead replace{} in moc{} uic{} rcc lrelease{} with '-qt5', 'qt4' 
then '', but that might be more challenging than it is worth.

OK, I've looked in the qt3-devel-3.3.8b-37.fc14 patch and see all the 
files without a "qt4" or "qt5" suffix.

I don't know what Qt developers were thinking other than perhaps major 
reworks associated with changes in ownership.  That software has been 
acquired a couple times or more now.
