Hi Rick
If you are using ./configure with every build (& updating a local git
copy/clone) then you are likely doing this infrequently & so should be
running "make clean" & "make distclean" first..

A problem arises with transition from Qt4 to Qt5.. the Qt5 qmake fails
to "clean" Qt4 makefiles & moc files (AIUIK).
You can fix this by running make clean & distclean before upgrading Qt
or can use sometime similar to "./configure --qmake=/usr/bin/qtmake-qt4"
to then get "make clean & distclean" to run..
Then go back to your ./configure cmd afterwards..

If you do "git pull" inside your local mythtv source git repository, it
updates the mythtv & mythplugins folders. So your step (6) is not good.
