I think the complete rebuild is required every time you want to build
mythtv-light into a .deb.

I tried on my Production backend which is Debian 12 x86_64 to just do a git
pull on both packaging and mythtv repos and then checkout fixes/35.
Next I tried the build_package.sh and it flew through the build as very
little had changed.

i tried to install that .deb file and it did install cleanly, but
mythbackend would not run on reboot because it could not find
libmythtvexiv2.so...

Not sure what causes that, but this time I followed your 2 steps above and
also had to remove all the .pc files in /usr/lib/pkgconfig/

Then I rebuilt the mythtv-light package and it installed and worked
correctly.
