You mention latest fixes. If you are trying to run the latest 0.20 fixes 
branch, then you have grabbed the wrong branch from SVN (likely trunk). 
If you want to run trunk, then you might try updating your front ends 
with the bleeding mythtv-trunk packages from ATrpms. However, before 
doing any of this, I suggest that you back up your database.
