The error was due to there being an older version of mythtv installed on
the computer I was building on. In the mythtv.spec file there is a line

LIBS *= -L$temp%{_libdir}

which puts the libraries already on the computer ahead in the search order
of the ones just built, resulting in trying to link with the old versions.
I changed it to

LIBS = -L$temp%{_libdir} $LIBS

and the new libraries are found first.

I also had a problem with junk left over from a previous perl installation
so mythweather would not build, but that was fixed
by deleting the offending directory.

The third issue was a file that was built but not packaged. I had to
uncomment

%{_bindir}/mythffplay

under

%files common

section. I think this will need to be done to build from the latest git and
the library reorder is probably a good idea also.

After that it builds successfully with the latest from git. I will see how
it works tomorrow.
