That is tricky. I have a similar setup, running MythTv 0.20 from 
ATRPM's. In my case the SVN version from 2006-09-18 is compatible 
(MYTH_PROTO_VERSIONS) with the 0.20 ATRPM's version installed on my server.
So I am building the SVN version and simply running just the program 
"mythtv" with the name of a video file to play on my unichrome box from 
that SVN source tree setting LD_LIBRARY_PATH to point to the appropriate 
SVN source tree's libraries. I enclose a copy of my "hacked" run script 
that I use to perform a test run on my Unichrome box.
I don't need to replicate and databases or mod the running system at all.
