In case it triggers any ideas, I've tracked this down a bit further.   
There is actually an error message above the failure I listed above -  
coming from the fact that the build does not have a value for qt5_moc,  
even if I pass "--with-qt5-moc=/usr/lib64/qt5/bin/moc to ./configure.   
(I've also tried various combinations of dash and underscore, in case  
there is a typo somewhere replacing one with the other.)  I'm assuming  
this is working correctly for other folks, so I doubt it is a failure  
in the source code, but more likely a configuration issue on my part.

Any ideas?
