[mythtv] Can't compile master in SL7.1beta

[John Pilkington]

I have SL7rolling on a 'new' Core2Duo box, and a working self-build of a 
recent qt4 master under SL7.0 on a similar box.  Repos enabled are 
SL7rolling etc or SL7x etc, epel, nux-dextop, elrepo.   ansible doesn't 
know SL but installed some packages, and after editing specfile 
references to qt and installing the packages listed as missing, the 
build process starts.  Tarball v0.28-pre-2807-g9efb747.

But then it fails.  Problems listed a little earlier are:

To me, these don't look to be qt5-related.  Should I just wait for SL7.1 
release? (Or qt5-based *buntu)? :-)

TIA
